![**Balanced Chemical Equation for the Formation of Zinc Chloride from Zinc and HCl**
To achieve a balanced equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) to form zinc chloride (ZnCl₂), follow these steps:
1. **Identify the reactants and products:**
- Reactants: Zinc (Zn) and Hydrochloric acid (HCl)
- Products: Zinc chloride (ZnCl₂) and Hydrogen gas (H₂)
2. **Write the unbalanced equation:**
\[
\text{Zn} + \text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2
\]
3. **Balance the equation:**
\[
\text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2
\]
**Explanation:**
- Zinc displaces hydrogen from hydrochloric acid, resulting in the formation of zinc chloride and hydrogen gas.
- Two moles of HCl are required for each mole of Zn to ensure both chlorine atoms in ZnCl₂ are accounted for, balancing the chemical equation.
**Visual Aids:**
No graphs or diagrams are present in the image. The textual content focuses on the chemical balancing process.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0cdee159-7a1f-47b8-b941-49ee717f4b32%2Ff4e6cbe2-de28-4d61-8a75-71c7f687216e%2Fi73tpoo_processed.jpeg&w=3840&q=75)
