O.S of Mn = 3+
O.S. of Cl = 7+
O.S. of O = 2-
Oxidation state of any element in its elemental state is 0
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.
In FeBr3, iron (Fe) has an oxidation state of +3 and bromine (Br) has an oxidation state of -1. Each bromine atom contributes -1 oxidation state, and since there are three bromine atoms, the total is -3, balancing the +3 oxidation state of iron for the compound to be neutral.
In CuCl2, the oxidation state of copper (Cu) is +2, and the oxidation state of chlorine (Cl) is -1. This is because the overall charge of the compound is 0, and there are two chloride ions each with an oxidation state of -1 to balance the +2 charge of copper.
In the compound MgBr2, magnesium (Mg) has an oxidation state of +2 and bromine (Br) has an oxidation state of -1. This is because the overall charge of the compound is neutral, so the sum of the oxidation states of each element must equal zero.
The hydrogen atoms are each in the 1+ oxidation state. The oxygen is in it's 2- oxidation state.
Sulfur has an oxidation state of +4 in SO3^2-. Each oxygen atom has an oxidation state of -2.
Oxidation state of any element in its elemental state is 0
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.
There are three elements, carbon, oxygen and hydrogen. Carbon's oxidation number is -4, each hydrogen is +1 and oxygen is +2.
In Mg2P2O7, magnesium (Mg) has an oxidation state of +2, phosphorus (P) has an oxidation state of +5, and oxygen (O) has an oxidation state of -2. The sum of the oxidation states for each element in the compound must equal zero due to its neutrality.
In FeBr3, iron (Fe) has an oxidation state of +3 and bromine (Br) has an oxidation state of -1. Each bromine atom contributes -1 oxidation state, and since there are three bromine atoms, the total is -3, balancing the +3 oxidation state of iron for the compound to be neutral.
In CuCl2, the oxidation state of copper (Cu) is +2, and the oxidation state of chlorine (Cl) is -1. This is because the overall charge of the compound is 0, and there are two chloride ions each with an oxidation state of -1 to balance the +2 charge of copper.
In the compound MgBr2, magnesium (Mg) has an oxidation state of +2 and bromine (Br) has an oxidation state of -1. This is because the overall charge of the compound is neutral, so the sum of the oxidation states of each element must equal zero.
The oxidation state for Ti in TiO2 is +4. This is because oxygen typically has an oxidation state of -2, and there are two oxygen atoms in TiO2 making the total oxidation state for oxygen -4, so the oxidation state for Ti must be +4 to balance it out.
The sum of oxidation states in a neutral compound is zero. In glucose (C6H12O6), carbon is the most electronegative element and has an oxidation state of -4 (H=+1, O=-2). With six carbon atoms, each with an oxidation state of -4, the total oxidation state for carbon is zero.
