What are the 20 most common chemistry lab substances?

Question

I found the melting points of 3 different unknown substances using the Thiele tube method, but now I can't find which are these substances because I would have to go through Perry's handbook, for example, and that would take forever. So maybe by knowing a couple of common substances would help... then I would look for their melting points and compare with my results.

oxalic acid
