Solution

Identify the endothermic and exothermic reaction.
a. HCl + NaOH → NaCl + H₂O + heat
Heat is released in the product side, as it mentioned in the above reaction. So, It is an exothermic reaction because heat is evolved in exothermic reaction.

b. $2 {KClO}_{3} (s) \overset{∆}{\to} 2 KCl (s) + 3 O_{2} ↑$
Heat is given in the product side to break the compound into simpler substances, as it mentioned in the above reaction. So, It is an endothermic reaction because heat is supplied in exothermic reaction.

c. CaO + H₂O → Ca(OH)₂ + heat
Heat is released in the product side, as it mentioned in the above reaction. So, It is an exothermic reaction because heat is evolved in exothermic reaction.

d. $C a {CO}_{3} (s) \overset{∆}{\to} C a O (s) + {CO}_{2} ↑$
Heat is provided in the product side to break the compound into simpler substances, as it mentioned in the above reaction. So, It is an endothermic reaction because heat is supplied in exothermic reaction.
