Answer :
When aluminum reacts with chlorine, aluminum chloride is produced. Here is how you can write, balance, and classify the reaction:
1. **Write the Reaction:**
The chemical equation for the reaction between aluminum and chlorine to produce aluminum chloride is:
\[2Al + 3Cl_2 \rightarrow 2AlCl_3\]
2. **Balance the Equation:**
In the unbalanced equation: \[Al + Cl_2 \rightarrow AlCl_3\]
Aluminum is balanced with 2 atoms on each side, and Chlorine needs 6 atoms on the right side. So, the balanced equation is:
\[2Al + 3Cl_2 \rightarrow 2AlCl_3\]
3. **Classify the Reaction:**
This reaction is a combination reaction, also known as a synthesis reaction. In this type of reaction, two or more reactants combine to form a single product. In this case, aluminum and chlorine combine to form aluminum chloride.
So, the balanced and classified reaction is:
\[2Al + 3Cl_2 \rightarrow 2AlCl_3\]
This reaction is a synthesis reaction where aluminum and chlorine react to produce aluminum chloride.
