Solution

The correct option is A 10.36 gm
Reaction:

$2 N H_{4} C l + C a (O H)_{2} \to C a C l_{2} + 2 H_{2} O + 2 N H_{3}$

$53.5$ gm of $N H_{4} C l$ produces $17 g$ of ammonia

So $32.6$ gm will give $17 \times \frac{32.6}{53.5} = 10.36$ gm NH $_{3}$

Hence, the correct option is $A$ .

The correct option is A 10.36 gm
Reaction:

$2 N H_{4} C l + C a (O H)_{2} \to C a C l_{2} + 2 H_{2} O + 2 N H_{3}$

$53.5$ gm of $N H_{4} C l$ produces $17 g$ of ammonia

So $32.6$ gm will give $17 \times \frac{32.6}{53.5} = 10.36$ gm NH $_{3}$

Hence, the correct option is $A$ .
