What will the reaction be?
If sulphuric acid is used instead of hydrochloric acid, what would be the salt formed?

Sorry but copper will not react with hydrochloric acid at all. Now if you used nitric acid then you would obtain a light blue solution, which is basically copper ions free in acid solution and if concentrated enough you would see brown NO2 gas evolving. There is also no reaction with sulfuric acid neither. This is basically due to copper being lower in the reactivity series.

The above answers are complete and total rubbish.
There is no reaction at all between copper metal and either dilute hydrochloric or dilute sulphuric acids.
This is because copper is below hydrogen in the reactivity series.

Reaction doesnt take place for either acids - Hcl nor H2So4,
This is because Cu cannot displace hydrogen from the acids as it is lower than hydrogen in the reactivity series.

2Cu + 2HCl = 2CuCl + H2
Cu + H2SO4 = CuSO4 + H2
Cuprous chloride (CuCl) & copper sulphate (CuSO4) are both easily water soluble salts, that can be obtained by evapoating the water from the dilute acid solution. If you evaporate slowly enough, you will see beautiful blue-green copper sulphate crystals forming.
Take care : both salts are poisonous, especially copper sulphate
