C2O42-COO -lCOO -O always has an oxidation states of -2.So if there are 4 O atoms, with -2 each, it gives a total of -8.since the charge on the ion is -2, the total carbon is +6, and there are 2, so each carbon is +3.C= +3
Terminal oxidation is oxidation on the end of a molecule. An example would be oxidation of a terminal carbon atom in a carbon chain.
zero for carbon in diamond
in CaCO3 carbon is in the 4+ oxidation state.
Graphite is pure carbon.So it has 0 oxidation state.

The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
There are NO carbon (C) atoms in potassium nitrate (KNO3). B.t.w. atoms always have an oxidation state to be zero.
Oxide is a monatomic (single-atom) ion consisting of an oxygen atom with a 2- charge (O2-). An oxide can also be just about any compound that contains oxygen in the 2- oxidation state. Oxalate is a polyatomic (multiple atom) ion consisting of 2 carbon atoms and 4 oxygen atoms, also having a total charge of 2- (C2O42-). It is derived from oxalic acid, H2C2O4.
Pure diamond and pure graphite are composed only of elemental carbon; therefore, the oxidation number of the carbon atoms is 0 by definition.
In K2C2O4 (potassium oxalate) both potassium and carbon have positive oxidation states. Potassium's is 1+ and carbon's is 3+.
Carbon is directly bonded with two hydrogen atoms and with an oxygen atom. All other elements are more electronegative than carbon. Therefore carbon has oxidation number +4.
