The gas evolved is hydrogen. Zinc is more reactive than hydrogen and hence when sulphuric acid is added to zinc , formation of zinc sulphate starts and hydrogen starts
evolving. The reaction is :-
Zn + H2SO4 --------> ZnSO4 + H2
On heating zinc sulphate (ZnSO4), both sulphur dioxide (SO2) and sulphur trioxide (SO3) are released. As a matter of fact, this is what always happens when sulphates are heated. Mind you, the decomposition of sulphites (SO32- )only releases sulphur dioxide!
Hydrogen gas is formed. Here is the chemical equation. Zn + H2SO4 = ZnSO4 + H2
Hydrogen is given off as it is in most reactions between and acid and a metal.
Zn + H2SO4 -- ZnSO4 + H2
Hydrogen.

zinc sulfate is formed H2 gas is evolved
nothing happens
hydrogen
Zn + H2SO4 --> ZnSO4 + H2Zinc + Sulfuric acid --> Zinc Sulfate + Hydrogen
Yes, exothermic reaction: Zn + H2SO4 --> ZnSO4 + H2 Zinc + Sulfuric acid --> Zinc Sulfate + Hydrogen(gas)

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.
coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.
Zinc + Sulphuric acid ----> Zinc sulphate + Hydrogen I think that's the answer. If it isn't, then sorry. I got the answer from... http://www.docbrown.info/page04/Y11revQs/acidreactionequationsFHanswers.htm
solid is it?
You would produce zinc sulphate, carbon dioxide and water.
