There is no carbon in H2O (water) molecule
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
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 carbon in K2CO3 is +4. This is because the oxidation number of potassium (K) is +1 and the oxidation number of oxygen (O) is -2, which allows for the calculation of carbon's oxidation number.
The oxidation number for carbon in CHI3 compound is -2. In CHI3, iodine has an oxidation number of -1 and hydrogen has an oxidation number of +1, which allows carbon to have an oxidation number of -2 to balance the overall charge of the compound.
The oxidation number for carbon in C2H6O is -3. This is calculated by assigning hydrogen an oxidation number of +1 and oxygen an oxidation number of -2, then applying algebra to determine the oxidation number of carbon.
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.
The oxidation number of carbon in formaldehyde (HCHO) is +2. In this molecule, oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. By applying the rules for assigning oxidation numbers in a compound, we can determine that carbon has an oxidation number of +2.
The oxidation number of carbon in CH3OH is -2. This is because hydrogen has an oxidation number of +1 and oxygen has an oxidation number of -2. By assigning these values to the other atoms in the molecule, we can determine that carbon must have an oxidation number of -2 to balance the overall charge of the molecule.
H is +1, O is -2 overall carbon will have an oxidation # of -3
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.
