Which of the following is a balanced equation for the reaction of Aluminum with Chlorine?
A$Al + Cl_2 \rightarrow AlCl_2$
B$Al + 3Cl \rightarrow AlCl_3$
C$2Al + 3Cl_2 \rightarrow 2AlCl_3$
D$3Al + 2Cl_2 \rightarrow Al_3Cl_4$
✓ Correct Answer: C — $2Al + 3Cl_2 \rightarrow 2AlCl_3$
Aluminum has a valency of 3 and chlorine gas is diatomic (Cl2). The balanced form is $2Al + 3Cl_2 \rightarrow 2AlCl_3$.
