(B) Let's analyze each option:$1$. Ammonia $(NH_3)$ is widely used as a refrigerant due to its high latent heat of vaporization. This statement is correct.$2$. Nitrolim is a mixture of calcium cyanamide $(CaCN_2)$ and carbon $(C)$. The option states $Ca(CN)_2$ (calcium cyanide), which is incorrect. Thus, this statement is incorrect.$3$. Superphosphate of lime is indeed a mixture of $Ca(H_2PO_4)_2$ and $CaSO_4 \cdot 2H_2O$. This statement is correct.$4$. The hydrolysis of nitrogen trichloride $(NCl_3)$ proceeds as follows: $NCl_3 + 3H_2O \rightarrow NH_3 + 3HOCl$. This statement is correct.Therefore, the incorrect statement is option $B$.
