How do you fined oxidation number of Zn in Zn(NO3)?

To find the oxidation number of zinc (Zn) in zinc nitrate (Zn(NO3)2), you start by recognizing that nitrate (NO3) has a charge of -1. Since there are two nitrate ions in the compound, the total negative charge is -2. To balance this, the oxidation number of zinc must be +2. Therefore, the oxidation number of Zn in Zn(NO3)2 is +2.
