Hydrogen takes +I and fluorine takes -I oxidation states in hydrogen fluoride.
100 will be oxidation no.in Fe2O3.
0 because all compounds have an oxidation number of 0. It's the ions (fe S O) that have oxidation numbers, The sum of these oxidation numbers always = 0 in a compound and hence a compound has a oxidation number of 0. :-) hope this helped....
0.
sum will be zero
0 they are neutral
HF
In a neutral compound, the sum of the oxidation numbers of the atoms in the compound is zero.
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.

The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. Cl has an oxidation number of -1. Therefore, Zn must have an oxidation number of +1.
HF is hydrogen fluoride.
It depends on the compound. Nitrogen has compounds in which the oxidation numbers range from -3 to +5.
The sum of the oxidation numbers is zero for the compound.
