Decomposition of Silver Bromide

The video tutorial explains the decomposition of silver bromide (AgBr) into silver and bromine gas. It guides viewers through counting atoms on each side of the equation and balancing it by adjusting coefficients. The process involves balancing bromine atoms first, followed by silver atoms, resulting in a balanced chemical equation. The tutorial concludes with a summary of the balanced equation.
