Let's see!
CuO + H2SO4 --> CuSO4 + H2O
========================
This reaction is what I think would theoretically happen here; a salt, copper sulfate, and water produced.
Copper Oxide reacts with Sulphuric acid to form Copper Sulphate and Water.
zinc and copper
None of them act violently with water, but the answer is Iron because Copper only reacts with dilute acids.
When dilute sulfuric acid reacts with copper(II) carbonate, blue copper(II) sulfate solution is produced.
Copper oxider
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.
2NaHCO3 + H2SO4 --> Na2SO4 + H2O(l) + CO2(g)
it reacts vigorously to form a calcium salt
Copper sulfate is dissociated in water.
it produces a gas
the copper sulfate reacts and changes colour
it is because hydrogen gas usually liberates when an acid reacts with metal
