Your adsense account is hooked up to Hubpages.com, because each code is individual and you have secured that code, but the other part means that your account is still pending. If it is pending, Google is not putting ads on your content, and it is not generating value. So no, your adsense is not working. I would highly recommend looking into the hubpages ad program, because it generates money a lot more generously than adsense ever will. There are more hubpages ads per content, and google will only generate revenue if you have lots of views, say, hundreds to thousands a day, and adsense is more appropriate for a blog or your own web domain, where you can control the number of ads you display (again, with a moderate amount of traffic).
I hope this helped.
