Homework Answers
Answer :
1) : Evidence of a chemical reaction : Blue colour of CuSO4 solution turned into colourless solution of ZnSO4 .
Balanced chemical reaction :
CuSO4 (aq.) + Zn (s) ------> Cu(s) + ZnSO4 (aq)
Balanced net ionic equation :
Cu2+ (aq) + Zn (s) -----> Zn2+ (aq) + Cu (s)
2) Cu metal can not displace Zn from ZnSO4 solution . So, reaction wouldn't happen .

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
