Question 7

Lithium, in Group 1, reacts with chlorine in Group 7. Lithium chloride is made. What is the balanced symbol equation for the reaction?

$Li+Cl→LiCl\text{Li} + \text{Cl} \rightarrow \text{LiCl}$

$2Li+Cl2→2LiCl2\text{Li} + \text{Cl}_2 \rightarrow 2\text{LiCl}$

$Li+Cl2→LiCl2\text{Li} + \text{Cl}_2 \rightarrow \text{LiCl}_2$

$2Li+Cl→Li2Cl2\text{Li} + \text{Cl} \rightarrow \text{Li}_2\text{Cl}$
