Explanation:
Empirical formula of the compound is the simplest ratio of elements present in the compound.
Empirical formula of compounds of chlorine with oxygen is as follows:
Compounds in which oxidation state of Cl is +1

Compounds in which oxidation state of Cl is +3

Compounds in which oxidation state of Cl is +4

Compounds in which oxidation state of Cl is +6

Compounds in which oxidation state of Cl is +7

Explanation:
the air you breathe is called carobon dioxide = co
Because if they are not balanced, then the amount of reaction is not equal to the amount of the product. You must have the same ratio of atoms on both sides of the equation because we are not losing moles of each element.
