1.describe what happens in combustion reaction.

2.compare and contrast. synthesis reactions and decomposition reaction

3.determine using figure 10, if zinc will displace gold in a chemical reaction and explain why or why not

4. think critically. describe one possible economic impact of redox reactions. how might that impact be lessend

12. main idea. classify each of the following reactions:

a. cao(s)+h2o(1)-> ca(oh)2(aq)
b. fe(s)+cuso4(aq)-> feso4 (aq) + cu(s)
c. c1oh8(1)+120^2 (g) -> loco2 (g)+ 4h2o(g)
d. naci (aq)+ agno3 (aq) -> nano3 (aq)+ agci(s)

e. nh4 no3 (s) -> n2o (g) -> nao(g)+2h2o(g)
