Write down two equations for the reactions of oxygen with simple and complex substances. determine the oxidation states and indicate the oxidizing agent and reducing agent

1 N2 (0) + O2 (0) = 2N (+2) O (-2) – nitric oxide (I)
O2 + 2e = 2O (-2) | LCM: 2 | 1
N2 – 2e = 2N (+2) | | 1
LCM – Least Common Multiple. It is not necessary to write the NOC, but there should be 2 in the middle.
2 S (0) + O2 (0) = S (+4) O (-2) – sulfur (IV) oxide
O2 + 2e = 2O (-2) INOK: 4I 2
S – 4e = S (+4) I I 1
3 4H (+) Cl (-) + O2 (0) = Cl2 (0) + 2H (+) 2O (-2)
salt to-that
O2 + 2e = 2O (-2) | LCM: 2I 1
Cl2 (-) – 2e = 2Cl (0) | I 1
4.2Cu2 (+) S (-2) + 3O2 (0) = 2Cu (+) O (-2) + 2S (+4) O (-2)
copper (I) sulphate copper (II) o. sulfur (IV)
O2 (-2) + 2e = 2O (-2) INOK: 6I 3
S (-2) – 6e = S (+4) I I 1
