Question

Calculate the oxidation number carbon in co2

Answer 1

Answer:

+4

Explanation:

Since oxygen is in group 6 on the periodic table, its valency is  

2 and hence so is its oxidation number.

But there are 2 oxygen atoms for each carbon atom so the total negative charge due the oxygen is  4

But since a molecule must have a net charge of zero in the free form, it implies that the oxidation number of the carbon atom must then be  + 4

Answer 2

Answer:

I think the oxidation of carbon is +4

Explanation:

c+2(-2)=0

c-4=0

so

c=+4
