Solution

## Chemical equation - $\mathrm{AgCl}\left(\mathrm{s}\right)\stackrel{\mathrm{Light}}{\to }\mathrm{Ag}\left(\mathrm{s}\right)+{\mathrm{Cl}}_{2}\left(\mathrm{g}\right)$Balancing the chemical equation - The unbalanced chemical equation must be obtained by writing the chemical formulae of the reactants and the products.Algebraic variables are assigned to each species (as stoichiometric coefficients) in the unbalanced chemical equation. The equations for each element are listed together to form a system of equations.Now that the smallest value of each variable is obtained, their values can be substituted into the chemical equation obtained.Reactant sideProduct sideAg = 1 x 2 = 2Ag = 1 x 2 = 2Cl = 1 x 2 = 2Cl = 2Balanced chemical equation - $\underset{\mathrm{Silver}\mathrm{chloride}}{2\mathrm{AgCl}\left(\mathrm{s}\right)}\stackrel{\mathrm{Light}}{\to }2\underset{\mathrm{Silver}}{\mathrm{Ag}\left(\mathrm{s}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_{2}\left(\mathrm{g}\right)}$
