What is the oxidation number of phosphorus in P4O6?

The oxidation number of phosphorus in P4O6 is +3. This is because oxygen typically has an oxidation number of -2, and the overall charge of P4O6 is zero. Therefore, the four phosphorus atoms must have a combined oxidation number of +12 to balance out the -12 from the six oxygen atoms.


What is the oxidation number to Fe2O3?

The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.

What is the oxidation number of oxygen (O) in the compound H2O?

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.
