An oxidation state is a number that is assigned to an element in a chemical combination.
Elemental oxygen 'O2' is in zero oxidation state . However, when oxygen is combined into moledcules, it is usually '-2' , but can be '-1'
H2SO4 is a compound and as such does not have an oxidation number. The individual atoms in this compound have oxidation number +1 for each hydrogen atom, +6 for sulfur, and -2 for each oxygen atom.
The oxidation number of each carbon atom in C6H8O6 is +4. Each hydrogen atom has an oxidation number of +1, and each oxygen atom has an oxidation number of -2.
The oxidation number of each oxygen atom in peroxide is -1.
The oxidation state of Hydrogen in the hydronium ion is 1+ and the oxidation state of oxygen is 2-
oxidation is caused with the addition of an oxygen atom

The oxidation number of each carbon atom in C6H8O6 is +4. Each hydrogen atom has an oxidation number of +1, and each oxygen atom has an oxidation number of -2.
Oxygen usually has an oxidation state of -2.
The oxidation number of each oxygen atom in peroxide is -1.
The oxidation state of Hydrogen in the hydronium ion is 1+ and the oxidation state of oxygen is 2-
The oxidation state of each oxygen atom in CO3^2- is -2, making a total of -6 for the three oxygen atoms. To neutralize this charge, the oxidation state of the carbon atom is +4.
The oxidation state of nitrogen (N) in nitric acid (HNO3) is +5. This is because hydrogen has an oxidation state of +1 in compounds, and oxygen usually has an oxidation state of -2. Since there are three oxygen atoms with a total oxidation state of -6 and one hydrogen atom with an oxidation state of +1, the nitrogen atom must have an oxidation state of +5 to balance out the charges and make the molecule neutral.
The oxidation number of oxygen in K2O2 is -1. Each oxygen atom in peroxide (O2^2-) has an oxidation number of -1.
If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.
The oxidation number of Zr in ZrOCl2 is +4. This is because oxygen usually has an oxidation number of -2, and there are two oxygen atoms in ZrOCl2. Additionally, the oxidation number of Cl is -1, and there is only one Cl atom in ZrOCl2, making the overall charge of Zr equal to +4.
