The oxidation state of oxygen in alkaline earth metal oxides is -2. Alkaline earth metals always have a +2 oxidation state, which means oxygen has to have a -2 oxidation state to balance the charges in the compound.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
The oxidation state of ruthenium in Ru2O3 is +3. Each oxygen atom has an oxidation state of -2, so for the compound to be neutral, the oxidation state of ruthenium must be +3.
The oxidation state of phosphate (PO4) is -3. This is because oxygen (O) typically has an oxidation state of -2, so there are 4 oxygen atoms in the phosphate molecule, contributing to a total charge of -8. This leaves the phosphorus atom with an oxidation state of +5 to balance the overall charge to -3.
The oxidation state of nitrogen in HNO3 is +5 because oxygen is assigned an oxidation state of -2 and hydrogen is assigned an oxidation state of +1. The sum of the oxidation states must equal the overall charge of the molecule (zero in this case for a neutral compound).
The oxidation state of F in HOF (hydrogen monofluoride) is -1. Hydrogen is typically assigned an oxidation state of +1, leaving the fluorine with an oxidation state of -1.
In peroxides, the oxidation state of oxygen is -1, while in superoxides, the oxidation state of oxygen is -1/2.
Oxygen usually has an oxidation state of -2.
The oxidation state for oxygen in the oxide ion (O2-) is -2. Oxygen typically has an oxidation state of -2 in most of its compounds.
The oxidation state of oxygen in its elemental form (O2) is 0.
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
The oxidation state of oxygen in O2PtF6 is zero. In a molecule of O2, the oxidation state of each oxygen atom is -2. Additionally, the compound PtF6 has a +6 charge, so the two oxygen atoms in O2PtF6 must have an oxidation state of zero to balance the overall charge of the compound.
The oxidation state of oxygen in the OCl- compound is -1. This is because the oxidation state of chlorine is +1 and the overall charge of the ion is -1. So, by assigning chlorine an oxidation state of +1, the oxidation state of oxygen must be -1 to balance the charge.
The oxidation state of Mo in MoO4 is +6. This is because each oxygen atom has an oxidation state of -2, and since there are four oxygen atoms in the compound, the total oxidation state contributed by oxygen is -8. In order to balance the charge of the compound, the oxidation state of Mo must be +6.
The oxidation number of hydrogen in H2O is +1 and the oxidation number of oxygen in H2O is -2.
The oxidation state of oxygen (O) in BaFeO4 is -2. This is because oxygen typically has an oxidation state of -2 in most compounds. Since there are four oxygen atoms in BaFeO4, the overall charge contribution from oxygen is -8.
The oxidation state of oxygen in H2O2 (hydrogen peroxide) is -1. Each hydrogen atom has an oxidation state of +1, so the total oxidation state must add up to zero in a neutral molecule.
