The oxidation number of H in H2O is +1, and that of O is -2. Since there are three H2O molecules, the total oxidation number would be 3(+1) + 3(-2) = -3.
The oxidation number of hydrogen in H2O is +1, so for 6 molecules of H2O, the total oxidation number for 6H2O would be +12.
Water, or H2O is a free-standing neutral compound, so it's oxidation number is 0. Its atoms have oxidation number though. Hydrogen's oxidation number in water is +1, and oxygen's is -2.
The oxidation number of oxygen in H2O (water) is -2. Oxygen typically has an oxidation number of -2 in most compounds. In H2O, there are two hydrogen atoms each with an oxidation number of +1, resulting in a total charge of 0 as oxygen contributes -2.
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.

There is no carbon in H2O (water) molecule
The oxidation number of oxygen in H2O (water) is -2. Oxygen typically has an oxidation number of -2 in most compounds. In H2O, there are two hydrogen atoms each with an oxidation number of +1, resulting in a total charge of 0 as oxygen contributes -2.
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
In the compound H2O, the oxidation number of hydrogen is +1 and the oxidation number of oxygen is -2. This is because in compounds, the sum of the oxidation numbers must equal zero.
The oxidation number of oxygen in water (H2O) is -2. This is because hydrogen typically has an oxidation number of +1, and the overall charge of water is neutral.
The oxidation number of an atom in a molecule of water (H2O) is determined based on the electronegativity of the atoms involved. In water, oxygen typically has an oxidation number of -2, while each hydrogen atom has an oxidation number of +1.
The oxidation number of oxygen (O) in the compound H2O (water) is -2. Hydrogen typically has an oxidation number of +1 in compounds, so the two hydrogen atoms in water have a combined oxidation number of +2. Since the overall charge of the compound is neutral, the oxidation number of oxygen must be -2 to balance out the charge.
The oxidation number of iron in the brown ring complex is +2. This complex is [Fe(H2O)5NO]2+ where the iron atom is in the +2 oxidation state.
In the combustion of H2S (hydrogen sulfide) to form H2O and S (sulfur), the oxidation number of sulfur changes from -2 in H2S to 0 in S.
