it is three
In N2O3, the oxidation state of nitrogen is +3 because oxygen is usually assigned an oxidation state of -2, and there are three oxygen atoms in N2O3. The sum of the oxidation states in a neutral compound should be zero, so the oxidation state of nitrogen must be +3 in order to balance the -6 from the three oxygen atoms.
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
The oxidation number of phosphorus in PL3 is -3. Each hydrogen has an oxidation number of +1, so in order for the overall charge of the compound to be neutral, phosphorus must have an oxidation number of -3.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
The oxidation number of B in H3BO3 is +3. Each hydrogen atom has an oxidation number of +1, and the overall molecule has a neutral charge. Since oxygen has an oxidation number of -2, the oxidation number of B must be +3 in order to balance the charges.
In N2O3, the oxidation state of nitrogen is +3 because oxygen is usually assigned an oxidation state of -2, and there are three oxygen atoms in N2O3. The sum of the oxidation states in a neutral compound should be zero, so the oxidation state of nitrogen must be +3 in order to balance the -6 from the three oxygen atoms.
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
The oxidation number of phosphorus in PL3 is -3. Each hydrogen has an oxidation number of +1, so in order for the overall charge of the compound to be neutral, phosphorus must have an oxidation number of -3.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
The oxidation number of B in H3BO3 is +3. Each hydrogen atom has an oxidation number of +1, and the overall molecule has a neutral charge. Since oxygen has an oxidation number of -2, the oxidation number of B must be +3 in order to balance the charges.
The oxidation number for the compound MO can vary depending on M. In general, oxygen has an oxidation number of -2. Therefore, you would need to know what element M represents in order to determine the oxidation number for MO.
The oxidation number of Iodine (I) in HI (hydroiodic acid) is -1. In binary compounds with hydrogen, hydrogen is assigned an oxidation number of +1. Therefore, the oxidation number of Iodine must be -1 in order for the overall compound to be neutral.
The oxidation number of sulfur (S) in SO2 is +4. Each oxygen atom has an oxidation number of -2, so in order to balance the charges, sulfur must have an oxidation number of +4.
The oxidation number of carbon in glucose is +4. This is because in glucose (C6H12O6), each oxygen atom has an oxidation number of -2 and each hydrogen atom has an oxidation number of +1, so the carbon atoms must have an oxidation number of +4 in order to balance the overall charge of the molecule.
MnO2: oxidation number +4KMnO4: oxidation number +7
The number is known as the oxidation number. It indicates the number of electrons that an atom has gained, lost, or shared in order to form a chemical bond in a compound.
