1. write the balanced equation for the reaction between zinc and acetic acid?
2. classify the reaction between zinc and acetic acid and explain, in general terms, what happens during this type of reaction?
3. give an example of a type of element and a type of compound that are likely to participate in this type of reaction?

U cant medal people on . U can only do that on Openstudy and your answers are " 1) Zn(s) + 2 HO2CCH3(l) --> Zn(O2CCH3)2 + H2(g) 

There are two half reactions: 
Zn -->Zn (2+) + 2e- 
2e- + 2 H+ --> H2 

(the acetic acid ionized to form H+ and acetate- ions) 

2) It's a red-ox (reduction-oxidation) reaction. The Zn gives up 2 electrons to the 2 hydrogen atoms. In general one element loses electrons and another gains electrons. The element gaining the electrons is the oxidizer and the element losing them is the reducing agent. The oxidizer becomes reduced and the reducing agent becomes oxidized. 

3) Hydrocarbons and oxygen."
