Question

Zn(s)+H2So4(aq) rise to znso4(aq)+H2(g)is an example of

Answer 1

Zn(s)+H2SO4(aq) rise to ZnSO4(aq)+H2(g) is an example of evolution of gas.

• The reaction Zn(s)+H2SO4(aq) →ZnSO4(aq) + H2(g) is a displacement reaction in which Zinc displaces H2 to form ZnSo4. As a result, H2 gas is the evolved as a result of this reaction. Hence, the correct option is evolution of gas.
• Other options, such as precipitation reaction, is not correct as it is a displacement reaction and is exothermic.
