The is no such substance as 'CaO2'.

However, if you mean 'CaO' (Calcium oxide/ lime), then the oxidation number of calcium is '+2'.

What is the oxidation state of an individual carbon atom in CaCO3?

The oxidation state of an individual carbon atom in CaCO3 is +4. This is because the oxidation state of Ca is +2, and the oxidation states of O are typically -2. The sum of the oxidation states for CaCO3 must equal 0, so the oxidation state of carbon in this compound must be +4.


What is the oxidation number O in cao2?

-1. In simple inorganic compounds other than peroxides and superoxides, oxygen almost always has an oxidation number of -2, but since calcium cations always have an oxidation number of +2, in this compound, the two oxygen atoms must have only -1 charge each. This compound is calcium peroxide, one of the exceptions noted above.


What is the chemical formula for calcium perchlorate?

Ca(ClO4)2 is calcium perchlorate.It is more often referenced as calcium perchlorate tetrahydrate = Ca(ClO4)2 . 4 (H2O)


What is the oxidation number for S in caso3?

The oxidation number for Sulfur (S) in CaSO3 is +4. This is because Calcium (Ca) has an oxidation number of +2 and Oxygen always has an oxidation number of -2. By setting up the equation Ca(+2) + S(x) + 3O(-2) = 0, we find that x = +4 for Sulfur.


What is the oxidation number of cac2o4?

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.
