Question

Verified by Toppr

Answer 1

Phosphine acetylene and ammonia can be formed by treating water with $C a_{3} P_{2}, C a C_{2}, M g_{3} N_{2}$
$C a_{3} P_{2} + 6 H_{2} O \to 3 C a (O H)_{2} + 2 P H_{3}$ (Phosphine)
$C a C_{2} (s) + 2 H_{2} O (l) \to C a (O H)_{2} (s) + C_{2} H_{2} (g)$ (Acetylene)
$M g_{3} N_{2} + 6 H_{2} O \to 3 M g (O H)_{2} + 2 N H_{3}$ (Ammonia)
Hence option B is correct.

Answer 2

Phosphine acetylene and ammonia can be formed by treating water with

C a_{3} P_{2}, C a C_{2}, M g_{3} N_{2}

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

(Phosphine)

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

(Acetylene)

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

(Ammonia)
Hence option B is correct.

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

$M g_{3} P_{2}, A l_{4} C_{3}, L i_{3} N$

$C a_{3} P_{2}, C a C_{2}, M g_{3} N_{2}$

$C a_{3} P_{2}, C a C_{2}, C a C N_{2}$

$C a_{3} P_{2}, M g_{2} C, N H_{4} N O_{3}$

Solution

$C a_{3} P_{2}, C a C_{2}, M g_{3} N_{2}$
