Using the Method of Electric Balance to Determine Oxidation States and Balance the Reactions

To determine the oxidation states and balance the given chemical reactions using the method of electric balance, we will first identify the oxidation states of the elements involved in the reactions and then balance the reactions accordingly.

Reaction 1: Mg + H2SO4 -> H2S + MgSO4 + H2O

1. Identifying Oxidation States: - In the reaction, magnesium (Mg) is oxidized, and sulfur (S) undergoes reduction. - The oxidation state of magnesium changes from 0 to +2, and the oxidation state of sulfur changes from +6 to -2.

2. Balancing the Reaction: - The balanced chemical equation for the reaction is: ``` Mg + H2SO4 -> H2S + MgSO4 + H2O ```

Reaction 2: CuSO4 + NOOH -> Cu(OH)2 + Na2SO4

1. Identifying Oxidation States: - In this reaction, copper (Cu) undergoes a change in oxidation state, while nitrogen (N) and oxygen (O) are involved in the reaction.

2. Balancing the Reaction: - The balanced chemical equation for the reaction is: ``` 3CuSO4 + 2NOOH -> Cu(OH)2 + Na2SO4 + N2O5 ```

These balanced chemical equations represent the reactions and the oxidation state changes for the given chemical reactions.
