Platinum is +4, chlorine is -1
For PtCl6^2-, let x be the oxidation number of Pt, and -1 be the oxidation number of Cl. Since there are 6 Cl atoms each with an oxidation number of -1, the sum of the oxidation numbers must equal the charge of the ion, which is -2. Therefore, x + 6(-1) = -2. Solving for x, we get x = +4. So, the oxidation number of Pt in PtCl6^2- is +4.
The oxidation state of calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
This oxidation state is 1.
The oxidation state of Cl in HClO3 is +5. This is because the sum of the oxidation states in a neutral molecule must be zero, and since H has an oxidation state of +1, O has an oxidation state of -2, the oxidation state of Cl must be +5 in order to balance the charges.

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 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.
2 oxidation state
O = -2 oxidation state H = +1 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
Platinum is connected to two anionic Chloride ligands and two neutral Ammine ligands Platinum = +2 oxidation state Chlorine = -1 oxidation state Nitrogen = -3 oxidation state Hydrogen = +1 oxidation state
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
This oxidation state is 1.
