chemistry quiz help

Hi, all!

I have a timed midterm to do and I need someone to help me. I need someone thats really good at chemistry because I cant afford to fail this class. I’m transferring and I took a 5 week chemistry course and i pretty much set myself up for failure and now I’m so desperate for help. Please if anyone knows chemistry very well, I would appreciate the help.

The midterm will be on Gas Laws, Stoichiometry, naming, chemical reactions, etc. Please let me know if you can help.
