-1
The oxidation number for oxygen (O) in K2O2 is -1. In this compound, each oxygen atom has an oxidation number of -1, which is typical for peroxides like K2O2.
The oxidation state of K in K2O2 is +1. In this compound, each K atom has a +1 oxidation state and each O atom has a -1 oxidation state.
The oxidation number for O in K2O is -2. Oxygen typically has an oxidation number of -2 in most compounds. Since there are two oxygen atoms in K2O, the total oxidation number contributed by the oxygen atoms is -4.
Potassium peroxide is an inorganic compound with the molecular formula K2O2. It is formed as potassium reacts with oxygen in the air, along with potassium oxide (K2O) and potassium superoxide (KO2). O^- does not exist; O^2- is the monoatomic form of the oxide ion; peroxide is [O-O]^2- (O-O) single bond, superoxide [O-O]^- (bond order =1.5) both are formed by adding two and one electron to O=O, respectively. Bonding best described using MO theory so not suitable at your level.
The oxidation number for H is +1, and the oxidation number for O is -1.

In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.
In KO2, O has an oxidation number of -1, K has an oxidation number of +1. In CO2, O has an oxidation number of -2, C has an oxidation number of +4. In K2CO3, O has an oxidation number of -2, C has an oxidation number of +4, and K has an oxidation number of +1. In the given reaction, the oxidation numbers for each atom remain the same as in their individual compounds.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number of oxygen (O) in most compounds, including sulfate (SO4), is typically -2. In Na2SO4, sodium (Na) has an oxidation number of +1. To calculate the oxidation number of oxygen in the compound, you would use the equation: 2(oxidation number of Na) + oxidation number of S + 4(oxidation number of O) = 0. By plugging in the known values, you can solve for the oxidation number of oxygen in Na2SO4.
The oxidation number of O in any elemental form (e.g. O2, O3) is zero. Typically in chemical compounds the oxidation number of O is -2 (oxide ion)
