Wait a sec. I think ppl are trying to discuss the same answers to different questions. For the T metal question, how many people got a question where it gives you the volumes of reactant? (namely 6cm3 and 18cm3)
And for the "2 blanks" question, how many people got a question asking which groups the lactic acid contains? Because i wrote Carboxylic acid, and alcohol. And many ppl are saying they wrote "alkyl" and alcohol. I mean.... where did alkyl pop up from? Theres definitely no alkyl group in lactic acid...
My bad. There is an alkyl group, but the question was identify the FUNCTIONAL GROUPS. Alkyls are not functional groups. Only OHs and COOHs are.
