Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.
oxygen compound=p
Carbon has an oxidation number of +4 in both carbonate and bicarbonate. Oxygen as usual has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, the ion CO3-2 has six negative charges from oxygen partly balanced by four positive changes from carbon for a net of -2, and HCO3-1 has six negative charges from oxygen partly balanced by one positive from hydrogen and needs for plus four from carbon for an overall value of -1.
The usual state of oxygen and hydrogen: they are gases at room temperature.
Minimum oxidation number: -3, Maximum oxidation number: 5
In most compounds oxygen will have an oxidation state of -2. The only exceptions are peroxides (-1), superoxides (-1/2), and compounds in which oxygen bonds with fluorine (+1 or +2).

+1 for hydrogen in most of the compounds and -1 in hydrides and hydrocarbons

The rule for hydrogen is that it normally has an oxidation state of +1, EXCEPT in metal hydrides, when it has an oxidation state of -1.Li is a metal, LiH is a metal hydride.Does that tell you what you need to know?
4 + 2 = 6, as usual.
Can structure mean number
When hydrogen and oxygen are kindled in the right quantities, then we mostly don't call the product a mixture. Rather we call it a compound. The most usual compound of hydrogen and oxygen is water. Its not important that the compound should have the properties of its constituting elements. If we that water as an example, then we all know that water is a non supporter of combustion whereas hydrogen and oxygen are highly inflammable gases.
+1 for K -2 for each O +7 for I
