Answer 2

Answer:

1. Adding zinc to copper sulfate will result in a displacement reaction that will create copper metal to precipitate as a solid. 

CuSO4(aq) + Zn(s) ---> ZnSO4 + Cu(s)

This reaction is quite exothermic too, meaning it will give off a lot of heat - enough to make it too hot to hold the reaction beaker in bare hands.

2. Chemical reaction of iron nail with copper sulphate solution in water. Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. ... Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).

3.its because the cu is more reactive than zn hence it will displace the zn in zinc sulphate and the solution will form be cupper sulphate

4.In the displacement reaction , it is only possible for the more reactive metal to displace the less reactive metal . Copper lies below iron in the reactivity series i.e. iron is more reactive than copper. Therefore, copper cannot displace iron from its salt solutions.

5.No reaction will take place as iron (Fe) is less reactive than zinc (zn) . Hence, iron will not displace zinc from its salt solution. No reaction will take place. this is because iron is less reactive then zinc.
