Fe + H2SO4 -----> FeSO4 + H2
The chemical reaction between iron and dilute sulfuric acid is a redox reaction. The iron reacts with the sulfuric acid to form iron(II) sulfate and hydrogen gas. The balanced chemical equation for this reaction is:
2 Fe + 3 H2SO4 -> Fe2(SO4)3 + 3 H2
Solid barium peroxide is added to cold dilute sulfuric acid BaO2(s) + H2SO4(aq) --> BaSO4(s) + H2O2(aq)
Iron + sulphuric acid ----> iron sulphate + hydrogen

Iron + sulphuric acid ----> iron sulphate + hydrogen
It depends on what has been added or how dilute it is.
Because there's a chemical reaction going on.

MgSO4+ H2O + CO2

Try it on your own. (Best answer for your problem is your action)
The chemical reaction is: CaCO3 + H2SO4 = CaSO4 + CO2 + H2O Carbon dioxide is released.

zinc sulfate is formed H2 gas is evolved
The most fizzing will come from the concentrated sulfuric acid, then dilute sulfuric acid, then the acetic acid.The amount of fizzing is due to the concentration of H+ in the solution, and concentrated sulfuric acid has the most H+ in solution. The dilute sulfuric acid has less (because it is dilute) and the acetic acid solution has the least of all because it is a weak acid rather than a strong acid.See the Related Questions for more information.
