(ii)`NaClO_(3)(aq)+SO_(2)(g) to`

Answer

To complete the given reaction equations, we will follow these steps:

### (i) Reaction of Calcium Oxychloride with Hydrochloric Acid

1. **Identify the Reactants**: The reactants are Calcium Oxychloride (Ca(OCl)₂) and Hydrochloric Acid (HCl).
2. **Write the Products**: When Calcium Oxychloride reacts with Hydrochloric Acid, it produces Calcium Chloride (CaCl₂), Water (H₂O), and Chlorine Gas (Cl₂).
3. **Write the Unbalanced Equation**:
\[ \text{Ca(OCl)}_2 + \text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{Cl}_2 \]
4. **Balance the Equation**: To balance the equation, we need to ensure that the number of each type of atom is the same on both sides. The balanced equation is:
\[ \text{Ca(OCl)}_2 + 4\text{HCl} \rightarrow \text{CaCl}_2 + 2\text{H}_2\text{O} + \text{Cl}_2 \]

### (ii) Reaction of Sodium Chlorate with Sulfur Dioxide

1. **Identify the Reactants**: The reactants are Sodium Chlorate (NaClO₃) and Sulfur Dioxide (SO₂).
2. **Write the Products**: When Sodium Chlorate reacts with Sulfur Dioxide, it produces Chlorine Dioxide (ClO₂) and Sodium Sulfate (Na₂SO₄).
3. **Write the Unbalanced Equation**:
\[ \text{NaClO}_3 + \text{SO}_2 \rightarrow \text{ClO}_2 + \text{Na}_2\text{SO}_4 \]
4. **Balance the Equation**: To balance the equation, we need to ensure that the number of each type of atom is the same on both sides. The balanced equation is:
\[ 2\text{NaClO}_3 + \text{SO}_2 \rightarrow 2\text{ClO}_2 + \text{Na}_2\text{SO}_4 \]

### Final Balanced Equations
1. **For the first reaction**:
\[ \text{Ca(OCl)}_2 + 4\text{HCl} \rightarrow \text{CaCl}_2 + 2\text{H}_2\text{O} + \text{Cl}_2 \]

2. **For the second reaction**:
\[ 2\text{NaClO}_3 + \text{SO}_2 \rightarrow 2\text{ClO}_2 + \text{Na}_2\text{SO}_4 \]
