Nitrogen forms five stable oxides with oxygen of the formula \(\mathrm{N}_2 \mathrm{O}, \mathrm{NO}, \mathrm{N}_2 \mathrm{O}_3, \mathrm{~N}_2 \mathrm{O}_4\) and \(\mathrm{N}_2 \mathrm{O}_5\). The formation of these oxides explains fully the
- A law of definite proportion.
- B law of partial pressure.
- C law of multiple proportion.
- D law of reciprocal proportion.
Answer & Solution
Correct Answer
(C) law of multiple proportion.
Step-by-step Solution
Detailed explanation
The weight of oxygen which combine with the fixed weight of nitrogen \((=28 \mathrm{~g})\) in \(\mathrm{N}_2 \mathrm{O}, \mathrm{NO}, \mathrm{N}_2 \mathrm{O}_3\), \(\mathrm{N}_2 \mathrm{O}_4\) and \(\mathrm{N}_2 \mathrm{O}_5\) are \(16,32,48,64,80 \mathrm{~g}\) respectively.…
