Chemistry Test 1 Chapters 1 & 2
I seriously doubt anybody will actually take the time to work all these out...including me.
By the way, the ^ thing is for the powers of stuff. I didn't know how to actually make the number small. And I left out the temperature stuff cuz I dunno how to make a degrees symbol. Oh well.
