C = +2 oxidation state
O = -2 oxidation state
The oxidation state of Co in CoCl2 is +2. This is because Cl is more electronegative than Co, causing it to have a 1- charge each. Since there are two Cl atoms, the oxidation state of Co must be +2 to balance the charges.
The IUPAC name for CoCl₂ is cobalt(II) chloride. In this compound, cobalt has a +2 oxidation state, which is indicated by the Roman numeral II in the name. The chloride ions (Cl⁻) balance the charge of the cobalt ion to form a neutral compound.

S = +4 oxidation state O = -2 oxidation state
The oxidation state is +3.
The oxidation state of Co in CoCl2 is +2. This is because Cl is more electronegative than Co, causing it to have a 1- charge each. Since there are two Cl atoms, the oxidation state of Co must be +2 to balance the charges.
The oxidation number of carbon in COCl2 is +2. In this compound, oxygen has an oxidation number of -2, and chlorine has an oxidation number of +1. Since the overall charge of COCl2 is zero, the oxidation number of carbon must be +2 to balance out the charges.
Cobaltic chloride refers to cobalt(III) chloride, where cobalt has an oxidation state of +3. Cobaltous chloride, on the other hand, refers to cobalt(II) chloride, where cobalt has an oxidation state of +2. The main difference is in the oxidation state of cobalt in the two compounds.
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The IUPAC name for CoCl₂ is cobalt(II) chloride. In this compound, cobalt has a +2 oxidation state, which is indicated by the Roman numeral II in the name. The chloride ions (Cl⁻) balance the charge of the cobalt ion to form a neutral compound.
The oxidation state of calcium is +2.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
O = -2 oxidation state H = +1 oxidation state
2 oxidation state
The oxidation state of calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
S = +4 oxidation state O = -2 oxidation state
