Question

Дам 20 балов.определите валентность азота в следующих соединениях N2O, NO2, HNO3, HNO2​

Answer 1

Ответ:

N2O = 2

NO2 = 4

HNO3 = 5

HNO2 = 3

Answer 2

Valence of Nitrogen in the following compounds:

To determine the valence of nitrogen in the given compounds, let's examine each compound individually:

1. N2O (Nitrous oxide): Nitrous oxide is a compound composed of two nitrogen atoms and one oxygen atom. The valence of nitrogen in N2O is +1.

2. NO2 (Nitrogen dioxide): Nitrogen dioxide is a compound composed of one nitrogen atom and two oxygen atoms. The valence of nitrogen in NO2 is +4.

3. HNO3 (Nitric acid): Nitric acid is a compound composed of one nitrogen atom, three oxygen atoms, and one hydrogen atom. The valence of nitrogen in HNO3 is +5.

4. HNO2 (Nitrous acid): Nitrous acid is a compound composed of one nitrogen atom, two oxygen atoms, and one hydrogen atom. The valence of nitrogen in HNO2 is +3.

In summary: - The valence of nitrogen in N2O is +1. - The valence of nitrogen in NO2 is +4. - The valence of nitrogen in HNO3 is +5. - The valence of nitrogen in HNO2 is +3.

I hope this helps! Let me know if you have any further questions.
