+1 for K, +5 for N, -2 for each O
+1 for K -2 for each O +5 for N
Oxidation number is 4, formula C3O2O=C=C=C=O
In KNO3 the oxidation number of potassium (K) is 1+, for nitrogen (N) it is 5+, and for each oxygen (O) it is 2-
Ru has oxidation number +8, O has oxidation number of -2
The overall oxidation number is -2 so the average oxidation number of O is -1.
+1 for K -2 for each O +5 for N
Oxidation number is 4, formula C3O2O=C=C=C=O
In KNO3 the oxidation number of potassium (K) is 1+, for nitrogen (N) it is 5+, and for each oxygen (O) it is 2-
Ru has oxidation number +8, O has oxidation number of -2
The overall oxidation number is -2 so the average oxidation number of O is -1.
Oxidation number of chlorine is +7. oxidation number of O is -2.
The oxidation number for H is +1, and the oxidation number for O is -1.
Oxidation number of Si is +4.Oxidation number of O is -2.
It is not possible to know the oxidation number in an formula with more then 2 unknowns such as OCN- you only know O is -2.
Oxidation number of Nb is +4. Oxidation number of O is -2.
Oxidation number of C is +3. Oxidation number of O is -2.
Oxidation number of N is +1. Oxidation number of O is -2.
