You are not going to receive help by posting this topic. Here is a suggeston or two on how to gain help:
1) DESCRIBE your problem. "I need help" tells us nothing and people are likely to be turned away because they don't know how to help you.
2) Post in the correct forum - the chemistry forum.
3) Take a look at the host of notes on the main Bored Of Studies site. There are chemistry notes there.
