Greetings, W4S3L:, I'd like to welcome you and all the new students to the Chemical Forums,  but I want to ask you to review our Forum Rules{click}.  You already accepted the rules when you signed up for our forum, and you have to follow them, whether you agree with them or not, or even if you're unaware of them.

We want to see you do some work, on your own, and we'll help.  We don't dump complete answers, not for anyone, not for a high school student, nor a hard-working professional, nor even the home chemist working on their newest invention.

So let's get started.

What work have you done, to begin to solve this problem?  What plans do you have to address this task?  What have you learned recently, that you can use to solve this problem?

I'm going to assume the class assignment was not:  Go online and ask someone to do all the work.  So I feel we must make clear the tasks we expect from you.
