I'm really sorry but you shouldn't be asking anyone this question. I know chem is hard so you should put a little effort into the class. Save the money that you would be using to pay people and save it up as a big reward for passing chem class. Chemistry is valuable information that could help you in your future life. Please dont hate me for this. just trust me. If you put in the extra work then you will feel good about it when you pass the class. If the teacher find out that you cheated, it would probably go on your permanent record. Hope this helps
