Chemistry
In inorganic chemistry, compounds with OH generally are bases (NaOH, KOH, Al(OH)3, etc). In organic chemistry, an OH attached to a C is an alcohol. -COOH is an acid. C-O-C is an ether. RCOOH = acids ROR ethers RCOOR = esters RNH2 amines RCONH2 amides.

You are in great trouble. You are not taking notes, nor or reading the text, and yet you are taking chemistry. Look up Molarity. You will fail chemistry if you do not know about Molarity, M. M=molessolute/literssolution=3.51/1.2= you do the division.
