-2 for each Oxygen
+4 for each Carbon
The oxidation number of C in C2O4^2- is +3. This is because each O atom is assigned an oxidation number of -2, and the overall charge of the ion is -2, so the two C atoms must have a total oxidation number of +6 in order to balance the charge.
The oxidation number of Ca in CaC2O4 is +2 because Ca, a group 2 element, typically has a +2 oxidation state in compounds. The oxidation number of C in C2O4 is +3 because the overall charge of the oxalate ion is -2, and there are two C atoms, each with an oxidation state of +3 to balance the charge.
The oxidation number of sodium (Na) is +1. The oxidation number of carbon (C) in a compound is typically +4, except in the case of CO2 where it is +4 for each oxygen (O). In oxalate (C2O4), the overall charge is -2, so the oxidation number of oxygen (O) is -2 in this compound.
An oxidation number of 2 means the element has lost or gained 2 electrons in a chemical compound. The oxidation number is a measure of the element's ability to combine with other elements.
The oxidation state of carbon in C2O4^2- is +3. This is because oxygen usually has an oxidation state of -2, and the total charge of the ion is -2. By setting up the equation x(2) + 4(-2) = -2, you can solve for x= +3 for the carbon atom.

Zn is a d block element. Oxidation number of it is +2.
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.
Calcium is a element. Nitrate is a ion. Calcium shows +2.
Oxidation number of a free element is 0. Ex: Ag 2= 0
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
In MnCl2, the oxidation number of Mn is +2, as it is in the +2 oxidation state. The oxidation number of Cl is -1 each, as it is typically in the -1 oxidation state when bonded to metals such as manganese.
There are 3 elements. This is meta phosphoric acid.
