acid? HELP PLS!!? (i) Butenedioic acid (also called Maleic acid) is unsaturated. How do you describe a test to show this?

(ii) Draw the structural formula of the product that is formed in (i). Name the compound. (well i don't think you can draw here so perhaps you could help by telling me which elements got replaced by what, and which double bonds were broken to single bonds)

I would really appreciate if you could help me. Thanks...
another sub-question (opps)
(iii) When ethane-1,2-diol reacts with butenedioic acid, which functional group of the acid will be "attacked"? Name the new functional group formed in the new organic compound in the reaction.
