In H3PO3 each H is 1+ for a total of 3+. Each O is 2- for a total of 6-. So, there is 3+ and 6- giving a net of 3-. In order to make the molecule neutral, P must have an oxidation state of 3+.
The oxidation state of Rhodium (Rh) in the complex (PPh3)3RhCl is +1. This is because each triphenylphosphine ligand (PPh3) contributes -1 charge (-3 total), and the chloride ligand (Cl) contributes -1 charge. Since the overall charge of the complex is neutral, the oxidation state of Rh is +1.
In PPh3, each phosphorus atom has an oxidation state of +3. The overall charge of the molecule would be neutral since there are three phenyl (Ph) groups, each with a -1 charge, balancing the +3 charge of the phosphorus atom.
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.

To determine the number of electrons in the complex Cr(n5-C5H5)(CO)2(PPh3), we can apply the 18-electron rule. Chromium (Cr) in the zero oxidation state contributes 6 electrons. Each CO ligand donates 2 electrons (total of 4 from 2 CO), and the PPh3 ligand contributes 2 electrons. The n5-C5H5 (cyclopentadienyl) ligand donates 5 electrons. Thus, the total electron count is 6 (Cr) + 4 (from CO) + 2 (from PPh3) + 5 (from n5-C5H5) = 17 electrons.
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.
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
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.
