Answer 1

N вторая,О первая
Cl первая,О вторая
С первая,О первая
Ва первая,О первая

Answer 2

Valence of NO2+

The valence of NO2+ is +1. The nitrogen atom in NO2+ has a formal charge of +1, while the oxygen atoms have a formal charge of -1. This gives a total charge of +1 for the molecule. [[1]]

Valence of Cl2O

The valence of Cl2O is +2. The chlorine atom in Cl2O has a formal charge of +1, while the oxygen atom has a formal charge of -2. This gives a total charge of +2 for the molecule. [[2]]

Valence of PH3

The valence of PH3 is -3. The phosphorus atom in PH3 has a formal charge of -3, while the hydrogen atoms have a formal charge of +1 each. This gives a total charge of -3 for the molecule. [[3]]

Valence of CO

The valence of CO is 0. The carbon atom in CO has a formal charge of 0, while the oxygen atom has a formal charge of 0 as well. This gives a total charge of 0 for the molecule. [[4]]

Valence of BaO

The valence of BaO is +2. The barium atom in BaO has a formal charge of +2, while the oxygen atom has a formal charge of -2. This gives a total charge of 0 for the molecule. [[5]]
