1) The balanced chemical reaction for the decomposition of solid silver bromide is:

2 AgBr(s) -> 2 Ag(s) + Br2(g)

2) First, count the number of atoms of each element on both sides of the equation. There are 2 silver atoms, 2 bromine atoms, and 2 bromide ions on the reactant side, and 2 silver atoms and 2 bromine atoms on the product side.

3) To balance the equation, we need to adjust the coefficients in front of the reactant and product. Therefore, the balanced equation for the decomposition of solid silver bromide is 2 AgBr(s) -> 2 Ag(s) + Br2(g).
