Answer 1

$\huge\fbox\red{Answer}$

A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name.

Answer 2

Answer:

(a) The substance ‘X’ is calcium oxide. Its chemical formula is CaO.

(b) Calcium oxide reacts vigorously with water to form calcium hydroxide (slaked lime).

CaO (s) + H2O (l) → Ca(OH)2 (aq)

Calcium Oxide (Quick Lime) + Water → Calcium Hydroxide (Slaked Lime)
