History of Chemistry

The science of Chemistry started in 2000 B.C. – 300 A.D.

These are some of the significant discoveries that led to the development of Chemistry as a science.

Chemical Crafts

The earliest chemists were practical craftsmen. The drawings from ancient wall paintings show Egyptians mixing molten metals to make bronze, copper, gold, tin, iron, lead, silver and electrum.

300 – 1400

Alchemy

In their search for the formula to make gold, medieval alchemists developed many chemical compounds and valuable apparatus.

1400 – 1600

Paracelsus, a German physician and alchemist, laid the foundations of medical chemistry in the 16th Century by Using chemicals as medicines.

17th Century

Robert Boyle, an Irishman introduced rigorous scientific method to the study of chemistry, helping rid it of occult ideas of alchemy in the process.

18th Century

Apparatus used by Antoine Lavoisier in his precise experiments showed that combustion was reaction involving air and not the mythical fluid, phlogiston.

19th Century

The development of the periodic chart of elements first devised by Mendeleeve, was the chart with a list of elements by weight and groups them according to properties.

20th Century

In the 1920s came the discovery of how to “polymerize” or combine molecules like the nylon 66 component modeled below into long useful chains.

Introduction

Chemistry, the science that investigates the properties and transformations of substances, had its origins in the laboratories of alchemists. Alchemy eventually expired under the impact of science, but its tools and procedures were taken over in the 16th Century by the new study of medical chemistry. Men such as Paracelsus and Van Helmont gained shrewed insight into chemical laws as they attempted to find cures for bodily ailments. Lavosier’s provocative experiments with combustion in the 18th Century completed the transformation of chemistry into an exact science.

Most of the knowledge gathered by these men was in the field of inorganic chemistry. As late as the 19th Century, chemists believed that a mysterious “vital forces” was necessary to make substances like those created by living things, the so-called organic compounds, all containing carbon. However, in 1828, Friedrich Wohler produced the organic compound urea in a simple laboratory experiment. Synthetic organic compounds are among our most useful chemical products today. Their recent soaring proliferation has largely been due to the discovery of “polymerization”-a process that enables chemist to create new, tailor-made molecules and link them together to make plastics, textiles or medicines.

Branches of Chemistry

  1. Inorganic Chemistry is the study of compounds that do not contain carbon.
  2. Organic Chemistry is the study of compounds that contain carbon.
  3. Physical Chemistry is the study of heat, electricity, and other forms of energy in chemical processes.

Famous Men of Chemistry

These are the famous men of Chemistry:

  1. Democritus of Greece taught 2,300 years ago that all things were made of atoms.
  2. Roger Bacon, an English monk, saw the need for careful experimentation in alchemy. Alchemy was one of the earliest forms of chemistry. This ancient practice combined science, religion, philosophy and magic.
  3. Philippus Paracelsus promoted the use of chemistry in medicine during the 1500’s.
  4. Robert Boyle attacked the ancient theories of alchemy and became the first and real chemist.
  5. Antoine Lavoisier founded modern chemistry by explaining how oxygen forms compounds.
  6. Sir Humprey Davy discovered several elements and invested a safety lamp for miners.
  7. Jones J. Berzellius calculated atomic weight and began the use of modern chemical symbols.
  8. Dmitri Mendeleev discovered that an element’s properties depend on its atomic weight.
  9. Friedrich Wohler was the first chemist to make an organic compound in the laboratory.
  10. Thomas Graham a founder of physical chemistry and explained how gases mix with each other.
  11. Antoine Henri Becquerel discovered that uranium gives off rays similar to x-rays.
  12. Glenn T. Seaborg was one of the discoverers of artificial elements heavier than uranium.
  13. Melvin Calvin explained how plants make food by the process of photosynthesis.

Importance of Chemistry

Chemistry is the science dealing with materials, their composition, and the changes, which they undergo. Chemistry fits into our lives. It offers new chemical frontiers and tells us what benefits may flow from them. Chemistry contributes to our existence, our culture, and our quality of life. Chemistry is concerned with the changes we see around us like the rusting of iron, growing of grass, burning of wood and many more. Without these changes or chemical reactions our Planet Earth would be lifeless. A plant takes carbon dioxide from the air and water from the soil to produce carbohydrates through a wondrous series of chemical reactions called photosynthesis. All living processes are chemical reactions. Everything we use, wear, live in, ride in, and play with is produced through controlled chemical reactions. Chemists design reactions that will convert chemical substances we find around us into chemical substances that serve our needs.

Chemistry answers the needs of our society through a deep understanding of the factors that govern and furnish control of chemical reactions. It plays a critical role in man’s attempt to feed the world population, to top new sources of energy, to clothe and house humankind, to provide renewable substitutes for dwindling or scarce materials, to improve health and conquer disease, and to monitor and protect our environment. Because of this responsiveness to human needs, chemistry has become a crucial factor in the nation’s economic well being. Aside from that, our culture believes that learning about our place in the universe is not enough reason for encouraging scientific inquiry. Nothing concerns humans more than questions about the nature of life and how to preserve it. Since all life processes are brought about by chemical changes, understanding chemical reactivity is a vital foundation for our ultimate understanding of life. Thus chemistry, along with biology, contributes to human knowledge in areas of universal philosophical significance.

Bizarre Facts about Chemistry

Chemistry is a very interesting science and it is really made up of facts which seem too strange to be true. Here are some of the bizarre facts that might interest you from Strange and Bizarre Chemistry by Anne Marie Helmenstine, Ph.D, a Chemistry Expert:

  1. Liquid oxygen is blue
  2. Some radioactive elements really do glow.
  3. You can die from drinking too much water.
  4. If you mix half a liter of alcohol with half a liter of water, the volume of the mixture will be less than one liter.
  5. Liquid water is more dense than solid water (ice).
  6. You can melt a sample of the element gallium just by holding it in your hand.
  7. Under certain conditions, hot water will freeze more quickly than cold water.
  8. You can't solidify helium at normal pressures, even at absolute zero. (You can solidify it at extremely high pressure and low temperature.

      This chemistry survey is designed to introduce students to the world of chemistry. The principles of chemistry were first identified, studied, and applied by ancient Egyptians in order to extract metal from ores, make alcoholic beverages, glaze pottery, turn fat into soap, and much more. What began as a quest to build better weapons or create potions capable of ensuring everlasting life has since become the foundation of modern science. Take a look around you: chemistry makes up almost everything you touch, see, and feel, from the shampoo you used this morning to the plastic container that holds your lunch.

      General Chemistry is important in our course Hospitality Management not just in cooking also doing the housekeeping activities. You need to learn what chemical your are using to clean the dirt, it is dangerous or what.

      General Chemistry (sometimes called "Gen Chem" for short) is a course often taught at the highschool and introductory university level. At the university level, it is also sometimes used as a "weed out" course for disciplines (sometimes related, sometimes not) which are perceived to require a high level of intellectual rigor large course loads.

      RUSSELL BERNARDINO BSTM4. Chemistry is important because everything that we do is chemistry . Our body needs chemical reactions to function, and the most essential type of chemical reaction is photosynthesis where plants , algae and cyanobacteria absorb light , water and carbon dioxide to produce molecules needed for their growth. These molecules include sugars, enzymes and chlorophyll--and oxygen will be their waste product that is essential for us to live. Without chemistry different industries such as housing industry , construction , tourism , medical industry etc. Wouldn't be as well established as now. Everything that we touched, throughout our lives is touch by chemistry.

      Chemistry is the science that investigates the properties and transformations of substances. Chemistry is all around us, in everything we do, we eat and everything we own. Chemistry is essential to Nursing because it helps administer medicine to patients. Chemistry helps us nurses to know which medicines to give or not to give to patients as different medicines have different effects and reaction to the body as our bodies are the biggest and most functional laboratory. Nursing programs feature different chemistry courses, including biochemistry, pharmacology, general level chemistry and organic chemistry. All of these courses play an important role in helping nurses understand different organic compounds, chemical equations, chemical reactions and chemical processes. Therefore, chemistry knowledge allows nurses to understand the effects of different medicines when used alone or in combination with others.

      The importance of Chemistry in nursing profession is when we give medications to our clients/patients. Medicines were invented through the use of chemistry, it is made up of elements or compounds that helps the body to recuperate or recover from ailments. Chemistry also helps us in terms of machines or instruments that we use for diagnosing different diseases or checking the vital signs of a patient, for example, we use thermometers when we are getting the temperature of a person. The connection of thermometers in chemistry is that they have this element called mercury. It also teaches us the importance of our environment because it is said that a clean and healthy environment improves the health of a person and help him or her to recover faster than normal whenever he or she is ill. Lastly, without chemistry, for me it is impossible to understand anatomy and physiology (which is our major subject) or other science that involve in studying nursing because it is said that our body is a living laboratory and that it is made up of chemical reactions that are important in our daily lives.

      FULL ANSWER

      The study of chemistry only became truly scientific after discarding the baggage it inherited from the earlier practice of alchemy. A crucial step on this path was the development of a true unifying theory of the elements that explained their observed behavior and made testable predictions about the compounds they form. Applying this theory greatly eases the task of virtually every geologist, medical researcher and engineer in the world.

      Geologists apply their understanding of chemistry to explain the formation of certain minerals, such as hematite, that would be mysterious otherwise. Biologists could be said to work in applied organic chemistry, as life is virtually nothing but very sophisticated carbon-based chemistry. The importance of chemistry to the pharmaceutical industry, as well as to the petroleum industry and the materials fabrication economy, could hardly be overstated. The study of chemistry is also important for anyone interested in pursuing a career in advanced nursing or nutrition. Chemistry is basic to essentially every field of science. A working knowledge of chemistry informs medicine, energy production and the vast majority of industrial processes. A comprehensive theory of chemistry allows predictions to be made about how any substance in the universe will behave in the presence of any other substance. Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.

      Chemistry is the study of matter and the changes that material substances undergo. Of all the scientific disciplines, it is perhaps the most extensively connected to other fields of study. Geologists who want to locate new mineral or oil deposits use chemical techniques to analyze and identify rock samples. Oceanographers use chemistry to track ocean currents, determine the flux of nutrients into the sea, and measure the rate of exchange of nutrients between ocean layers. Engineers consider the relationships between the structures and the properties of substances when they specify materials for various uses. Physicists take advantage of the properties of substances to detect new subatomic particles. Astronomers use chemical signatures to determine the age and distance of stars and thus answer questions about how stars form and how old the universe is. The entire subject of environmental science depends on chemistry to explain the origin and impacts of phenomena such as air pollution, ozone layer depletion, and global warming. We are living our own life and chemistry is in every part and moment of our life. We must realize the importance of chemistry in our daily life. From waking up in the morning to the time of sleeping, chemistry moves with us like our shadow and even while we sleep, chemistry is there with us. If you know a little about the facts of chemistry, then you may realize the real-time importance of chemistry in our every moment of life. When we walk, when we take food, when we inhale & exhale (breathe), when we bath, when we drink, when we do any work that we do in our everyday life, everywhere and every time, chemistry is always with us. Now let’s have a glance at the presence of chemistry in every subject of our life.

General chemistry also touches upon the major applications of chemistry in industry and agriculture.

      Since general chemistry deals mainly with the chemical elements and compounds, it has often been called inorganic chemistry.

      Chemistry deals with such topics as the properties of individual atoms. Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. How atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.

      Why Study Chemistry?

      Chemistry is the study of matter and energy and the interaction between them. There are many reasons to study chemistry, even if you aren't pursuing a career in science. Chemistry is everywhere in the world around you! It's in the food you eat, clothes you wear, water you drink, medicines, air, cleaners... you name it. Chemistry sometimes is called the "central science" because it connects other sciences to each others, such as biology, physics, geology and environmental science.

      Chemistry is important because it helps in exploring things which are unknown to mankind. Chemistry is important because it explains the future behavior of plants and animals and all of us use chemicals directly or indirectly in our daily lives.

      We are using chemistry when we cook, when we wash, when we eat, when we get ready, when we play, when we think, as a matter of fact, we always use chemistry. Increasing our knowledge in chemistry is essential if we want to improve our daily lifestyle.

      Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

      Before understanding the importance of chemistry in general it is essential to know the importance of chemistry in everyday life.

      1. Everything on earth is made up of chemicals: you, your food, and the products you use in daily life such as soaps, perfumes etc. all are made up of chemicals. Life without chemicals is impossible.

      2. A number of changes that you observe are the result of chemical reactions like the rain, the change in the color of leaves, cleaning of any particular material in your house, all involve chemicals.

      3. The basic knowledge of chemistry is essential for all; you need to understand certain chemical reactions. When does your packet food expire? What disinfectants and repellents you should use to keep your house hygienic and healthy and so on.

However, anyone can understand the basics of how things work... and that's the study of chemistry. In a nutshell, the importance of chemistry is that it explains the world We're all chemists. We use chemicals every day and perform chemical reactions without thinking much about them. Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.

Organic chemistry is extremely relevant to biological sciences, like nutrition, medicine, and molecular biology; inorganic chemistry is important for geology and materials science; physical chemistry can provide the thermodynamic and quantum mechanical background required for upper-level physics courses and astrophysics. The connections are endless. Even if your main focus is not chemistry, it is likely that it will aid in your studies of other sciences.

      Perhaps science is not your field of study. It could be mathematics, computer science, or even art history. Chemistry is not only about the science itself. It provides students with skills such as logic and problem-solving, which are applicable to everything. It explains why the world is the way it is. When you use an ice-pack, you will be able to understand how it works. When baking, you’ll see not only how the oil sits on top of the water, but you will know why the two do not mix.

Though the list of subjects covered is typically broad, leading some to criticize both the class and the discipline as encouraging memorization, most general chemistry courses are firmly grounded in several fundamental physical rules for which the primary challenge is understanding when the rules are applicable.

Once admitted, students follow a prescribed progression in their second, third, and fourth year. To graduate, a student admitted to the HM major must complete the required courses as listed below in the chronological order thus completing all HM level 2 before starting HM level 3 and henceforth completing all HM level 3 before starting HM level 4 courses while also respecting the co- and prerequisites.

      Chemistry has a reputation for being a complicated and boring science, but for the most part, that reputation is undeserved. Fireworks and explosions are based on chemistry, so it's definitely not a boring science. If you take classes in chemistry, you'll apply math and logic, which can make studying chemistry a challenge if you are weak in those areas. However, anyone can understand the basics of how things work... and that's the study of chemistry. In a nutshell, the importance of chemistry is that it explains the world around you.

      Cooking

      Chemistry explains how food changes as you cook it, how it rots, how to preserve food, how your body uses the food you eat, and how ingredients interact to make food

      The relevance of chemistry in hospitality management is when it comes to mixing drinks and using household items to maintain the cleanliness of a hotel. Cooking is chemistry. Everything you can touch or taste or smell is a chemical. When you study chemistry, you come to understand a bit about how things work. Chemistry isn't secret knowledge, useless to anyone but a scientist. It's the explanation for everyday things, like why laundry detergent works better in hot water or how baking soda works or why not all pain relievers work equally well on a headache.

      General Chemistry. based on my experience, every topic involves chemistry is related in our daily lives and to our course Hospitality Management. At first, We all know that chemistry is only about mixing and experimenting chemicals but as you study chemistry , it is all about everything related in our everyday living and every topic is very much important to us to know and understand.

      Chemistry is very important because chemistry explains many stuff in this world like cooking, medicine and cleaning. It is important to learn chemistry because all of sciences involve matter.

      General chemistry courses typically introduce concepts such as stoichiometry, prediction of reaction products, thermodynamics, nuclear chemistry, electrochemistry, chemical kinetics, and many of the rudiments of physical chemistry. Though the list of subjects covered is typically broad, leading some to criticize both the class and the discipline as encouraging memorization, most general chemistry courses are firmly grounded in several fundamental physical rules for which the primary challenge is understanding when the rules are applicable.

      600 million is here and there ? I guess what I have a hard time ingmiaing, is how we would cope with the same kind of massive power outage here in the US. Nearly everything I do is dependent on electricity: cooking, fridge, everything related to work, and most especially, heating.I suspect I could cope with no air-conditioning should the outage hit in summer, as I could always sleep out on the porch. But were it below freezing in winter, I have no way whatever to heat the place without electricity even though the boiler runs on natural gas. There is a hookup for a generator (which I sold), so I suppose I could go out and buy one before an outage occurs, but if it does occur and I have none, I am out-of-luck. Imagine, no power to pump gas into your car; no electricity to run cash registers where I need to buy a generator; no traffic lights anywhere; and ultimately, no water when the pressure from the water company finally gives out.

      General Chemistry is important to my course be cause chemistry exist in all aspect of our lives. Part of the importance of chemistry is it explains how cleaning works. You use chemistry to help decide what cleaner is best for dishes, laundry, yourself, and your home. You use chemistry when you use bleaches and disinfectants and even ordinary soap and water. How do they work That's Chemistry

      General Chemistry is important also in HOSPITALITY Industry, because as Scientist said, chemistry exist in all aspect of our lives, we must have to learn about it to know what should we apply in the foods that we serve in customer, what chemicals should be used in cleaning. And how we can value our field in HM dept.

      As a student of General Chemistry I am at my peak part of knowing the real importance why do I have to take this subject to my course. It is because of the field I may enter in the near future. And this is just one of the importance of Gen Chem in our life; basically the food we eat, it is made up of chemicals and other kinds of mixtures that may tackle here in Chemistry. Just have to be patient with the solutions and other basics dealing with it.
