Question

example of exothermic reaction in equation​

Answer 1

Answer:

Given below are some examples of exothermic reactions in everyday life:

Coal is burnt simply for the large amount of energy available during its combustion. This exothermic chemical reactions can be explained as follows:

C(s) + O2(g) → CO2(g) + Heatenergy

When water is added to quick lime (CaO) for preparing whitewash, a considerable amount of heat is produced during the reaction. The heat produced warms up the water. This is one of the simple exothermic reactions.

CaO + H2 O → Ca (OH)2 + Heat.

When we add dilute hydrochloric acid to a test tube containing granulated zinc, hydrogen gas is evolved. The reaction is accompanied by the evolution of heat. This is one of the common exothermic reactions.

Zn + 2HCl → ZnCl2 + H2 + Heat.
