Nitrogen dioxide cannot be obtained from

Options

  1. AC u ( N O 3 ) 2
  2. BH g ( N O 3 ) 2
  3. CN a N O 3
  4. DA g N O 3

Correct answer

C. N a N O 3

Step-by-step solution

Nitrogen dioxide cannot be obtained from N a N O 3 . C u NO 3 2 → Δ C u O + 2 N O 2 ↑ + 1 2 O 2 ↑ H g NO 3 2 → Δ H g ↓ + 2 N O 2 ↑ + O 2 ↑ A g N O 3 → Δ A g + N O 2 ↑ + 1 2 O 2 ↑
