Exothermic reaction is the reaction in which heat is involved to complete the reaction

for example burning of natural gas

respiration process

Explanation:

Answer 2

Answer:

Explanation:

(i) A reaction in which heat is given away when

reactants are transformed into the products is

called as exothermic reaction.

(ii) e.g. formation of ice from water, dissolution of

sodium hydroxide in water.

(iii) When solid NaOH is dissolved in water, heat

is given out and therefore, the temperature

increases.

(iv) NaOH(s) + H2

O(l) → NaOH(aq) + Heat

Sodium

hydroxide

Water Sodium hydroxide
