ANSWER
EXPLANATION
Given that;
[tex]\text{ Ag}_{(l)}^{2+\text{ }}\text{ + 2Cl}_{(l)}^-\text{ }\rightarrow\text{ AgCl}_{2(s)}[/tex]
The equation above represents a direct combination of elements to give compound.
The subscripts attached to each element is incorrect because silver is a solid metal and it should exist in solid state.
Chlorine is a diatomic gas and the state which it should exist should be the gaseous state.
Hence, the new equation is
[tex]\text{ Ag}_{(s)}^{2+}\text{ + 2Cl}_{(g)}^-\text{ }\rightarrow\text{ AgCl}_{2(s)}[/tex]
