![### Balancing Chemical Equations
#### Activity: Balance the Chemical Equation
**Objective:**
Complete the balanced chemical equation for the reaction between a weak base and a strong acid.
**Given Reaction:**
\[ \text{KNO}_2(aq) + \text{H}_2\text{SO}_4(aq) \rightarrow \]
**Instructions:**
Use the tools provided below the equation box to input the correct coefficients and states of matter to balance the chemical equation. Remember that each element must have the same number of atoms on both sides of the equation.
**Interactive Elements:**
- **Number Pad**: Includes numbers 0-9 for inputting coefficients.
- **Charge Boxes**: Options to specify charges such as \(4^-\), \(3^-\), \(2^-\), \(1^-\), \(1^+\), \(2^+\), \(3^+\), and \(4^+\).
- **Chemical States Symbols**:
- \((s)\) for solid
- \((l)\) for liquid
- \((g)\) for gas
- \((aq)\) for aqueous
- **Chemical Elements**: Deselect buttons labeled \(H, S, K, N\) are included to input elements.
#### Example Walkthrough:
1. **Identify the reactants and products:**
- Reactants: Potassium nitrite (KNO₂) and sulfuric acid (H₂SO₄).
- Products: This reaction will produce potassium sulfate (K₂SO₄) and nitrous acid (HNO₂).
2. **Write the partial equation:**
\[ \text{KNO}_2(aq) + \text{H}_2\text{SO}_4(aq) \rightarrow \text{K}_2\text{SO}_4(aq) + \text{HNO}_2(aq) \]
3. **Balance the number of atoms for each element:**
- Potassium (K): 2 K atoms on both sides.
- Nitrogen (N): Ensure nitrogen is balanced.
- Oxygen (O): Adjust oxygen atoms to balance.
- Hydrogen (H): Ensure hydrogen atoms are balanced.
- Sulfur (S): 1 sulfur atom on both sides.
4. **Final Balanced Equation:**
- Insert the balanced coefficients to achieve equal atoms for all elements on](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffbb15d99-77db-4308-835f-20d2902f98e0%2F2e17c8a8-b4a8-4609-ac4c-e23221c83db2%2F6z62rb_processed.jpeg&w=3840&q=75)
