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.
The oxidation number of manganese depends on the particular compound in which manganese is present. The most common oxidation states are +2 as in MnCl2, + 4 as in MnO2, and + 7 as in potassium permanganate, KMnO4.

The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
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.
MnO2: oxidation number +4KMnO4: oxidation number +7
The way to tackle this to look at reactants and at the products, and this where oxidation numbers come in. Remembering that oxidation is loss of electrons and reduction is gain, (OILRIG is an acronym that is sometimes used). Mn metal is changed to Mn2+ so it is oxidised H in HCl has a +1 oxidation number and in H2 zero so it is reduced. Cl in HCL is at -1 and is -1 in MnCl2 so it is neither oxidised nor reduced.
The oxidation number of manganese depends on the particular compound in which manganese is present. The most common oxidation states are +2 as in MnCl2, + 4 as in MnO2, and + 7 as in potassium permanganate, KMnO4.
The reaction between NH3 (ammonia) and MnCl2 (manganese chloride) produces the complex compound [MnCl2(NH3)4], known as tetraamminechloridomanganese(II) chloride.

The chemical formula for manganese is Mn and for chlorine is Cl. When these two elements combine, they can form various compounds such as manganese(II) chloride (MnCl2) or manganese(IV) chloride (MnCl4), depending on the oxidation state of manganese.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The chemical formula for manganese II chloride is MnCl2. It consists of one manganese (Mn) ion with a +2 charge and two chloride (Cl) ions with a -1 charge each.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
