Balancing Chemical Equations for AgCl

The video tutorial explains the decomposition of silver chloride into silver and chlorine gas when exposed to sunlight. It demonstrates how to balance the chemical equation by adjusting coefficients to ensure equal numbers of each type of atom on both sides. The process involves balancing chlorine atoms first by changing the coefficient of AgCl, followed by balancing silver atoms. The tutorial concludes with a balanced equation and a brief summary.
