Solution

The correct option is A Ca(OH)2 (Calcium hydroxide) and NH4Cl (Ammonium chloride)
In a laboratory Ca(OH)2 and NH4Cl is used to produce ammonia. When a mixture of Ca(OH)2 and NH4Cl is heated, the products formed are NH3 gas, CaCl2 and H2O in the form of water vapour. The equation of the reaction is given below.


Ca(OH)2 +2NH4Cl→ 2NH3 + 2H2O + CaCl2
