( N H 4 ) 2 C r 2 O 7 on heating liberates a gas. The same gas will be obtained by

Options

  1. Aheating N H 4 N O 3
  2. Bheating N H 4 N O 2
  3. Ctreating H 2 O 2 with N a N O 2
  4. Dtreating M g 3 N 2 with H 2 O

Correct answer

B. heating N H 4 N O 2

Step-by-step solution

Here nitrogen gas is formed in both the processes as follows ( NH 4 ) 2 Cr 2 O 7 → Δ N 2 + Cr 2 O 3 + 4 H 2 O N H 4 N O 2 → Δ N 2 + 2 H 2 O
