Hummmm...lets find out the answer......so when zinc granules are added to dilute sulphuric acid then zinc reacts with dilute sulphiric acid to form zinc sulphate and produce hydrogen gas.............................................Zn+H2So4----------->Znso4 + H2

Gas Evolved:
The gas evolved when zinc granules are added to dilute sulphuric acid is hydrogen gas (H2).

Reaction Taking Place:
The reaction between zinc granules and dilute sulphuric acid is a redox reaction, where zinc acts as a reducing agent and sulphuric acid acts as an oxidizing agent. The balanced chemical equation for this reaction is as follows:

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)

The reaction can be explained in the following steps:

1. Displacement Reaction:
Zinc (Zn) being a more reactive metal than hydrogen (H2), displaces hydrogen from sulphuric acid. It reacts with sulphuric acid to form zinc sulphate (ZnSO4) and hydrogen gas (H2).

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)

2. Oxidation of Zinc:
In this reaction, zinc undergoes oxidation. It loses two electrons to form zinc ions (Zn2+).

Zn(s) → Zn2+(aq) + 2e-

3. Reduction of Hydrogen:
Hydrogen ions (H+) from sulphuric acid accept electrons from the zinc atoms to form hydrogen gas. Each hydrogen ion accepts two electrons to form hydrogen gas (H2).

2H+(aq) + 2e- → H2(g)

4. Formation of Zinc Sulphate:
The zinc ions (Zn2+) and sulphate ions (SO4^2-) combine to form zinc sulphate (ZnSO4), which remains dissolved in the solution (aq).

Zn2+(aq) + SO4^2-(aq) → ZnSO4(aq)

Overall Reaction:
The overall reaction can be represented as:

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)

The evolution of hydrogen gas can be observed as bubbles or effervescence during the reaction. The reaction is exothermic, releasing heat energy. The zinc sulphate formed remains in the solution as an aqueous solution.

It is important to note that this reaction should be performed with caution as it involves the production of flammable hydrogen gas.
