Balancing Chemical Equations

To balance the chemical equations provided, we'll start with the given equations and balance them accordingly.

1) Cu + HNO3 = Cu(NO3)2 + NO + H2O

To balance this equation: - 2Cu + 4HNO3 = 2Cu(NO3)2 + 2NO + 2H2O

The balanced equation is: ``` 2Cu + 4HNO3 = 2Cu(NO3)2 + 2NO + 2H2O ```

2) H2SO4 + Mg = MgSO4 + H2S + H2O

To balance this equation: - H2SO4 + Mg = MgSO4 + H2S + H2O

The balanced equation is: ``` H2SO4 + Mg = MgSO4 + H2S + H2O ```

The balanced chemical equations are provided based on the given reactions If you have any further questions or need additional assistance, feel free to ask!
