Question

Give an example of a reaction where a gas is evolved. Write its balanced chemical equation.

Answer 1

react a metal with acid u will get hydrogen gas

Zn + H2SO4 ------- ZnSO4+ H2

Answer 2

Answer :

An example of a reaction where a gas is evolved is :

Zinc + Sulphuric acid –> Zinc Sulphate + Hydrogen

Zn + H2SO4 –> ZnSO4 + H2

Here, the hydrogen gas is evolved.

The equation is balanced.
