Silver chloride is a compound with the chemical formula AgCl. It is a white, insoluble solid.
Since it's already a single compound, there's no need for a balanced chemical equation.
However, if you're interested in how silver chloride is formed, the balanced chemical equation for the reaction between silver ions (Ag+) and chloride ions (Cl-) is:
Ag+ (aq) + Cl- (aq) → AgCl (s)
This equation shows that one silver ion reacts with one chloride ion to form one molecule of silver chloride.
