Question
**Balancing Chemical Equations:** **A) Under Acidic Conditions:** Given Chemical Equation: \[ \text{H}_3\text{AsO}_3\text{(aq)} + \text{I}_2\text{(aq)} \rightarrow \text{H}_3\text{AsO}_4\text{(aq)} + \text{I}^- \] Steps to Balance: 1. **Identify the oxidation and reduction components.** 2. **Balance the equation for atoms and charge using H\(^+\) for acids.** **B) Under Basic Conditions:** Given Chemical Equation: \[ \text{Cu(OH)}_2\text{(s)} + \text{N}_2\text{H}_4\text{(aq)} \rightarrow \text{Cu(s)} + \text{N}_2\text{(g)} \] Steps to Balance: 1. **Separate the reaction into half-reactions.** 2. **Balance atoms and charge using OH\(^-\) for bases.** **Note:** The balancing process involves ensuring that the number of atoms for each element and the charges are equal on both sides of the equation.
