Question

Вопрос 6 Расположите химические формулы веществ в порядке возрастания в них валентности азота. Расположите элементы в правильном порядке: 1 NO 2 NH3 3 NO2 4 N2O

Answer 1

Ответ:

3) NO2;

2) NH3;

1) NO;

4) N2O.

Answer 2

The order of nitrogen valencies in the given chemical formulas is as follows:

1. NO (nitric oxide) - Nitrogen has a valency of +2 in this compound. [[1]] 2. NH3 (ammonia) - Nitrogen has a valency of -3 in this compound. [[2]] 3. NO2 (nitrogen dioxide) - Nitrogen has a valency of +4 in this compound. [[3]] 4. N2O (nitrous oxide) - Nitrogen has a valency of +1 in this compound. [[4]]

Therefore, the correct order of the chemical formulas in terms of increasing nitrogen valencies is: N2O, NO, NO2, NH3.
