Phosphine, acetylene and ammonia can be formed by treating water with :

Question

Verified by Toppr

Answer 1

Correct Answer: Option B

Explanation:

The chemical formula of Phosphine is $P H_{3}$ ; Acetylene is $C_{2} H_{2}$ and Ammonia is $N H_{3}$ .
Formation of Phosphine:

$C a_{3} P_{2} + 6 H_{2} O \to 3 C a (O H)_{2} + 2 P H_{3}$

Formation of Acetylene:

$C a C_{2} (s) + 2 H_{2} O (l) \to C a (O H)_{2} (s) + C_{2} H_{2} (g)$

Formation of Ammonia:

$M g_{3} N_{2} + 6 H_{2} O \to 3 M g (O H)_{2} + 2 N H_{3}$
