(b)
Interpretation:
The balanced equation for the decomposition reaction of solid tin
Concept introduction:
A chemical reaction is a process in which rearrangement of atoms or ions takes place between two reacting species. A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on both sides of the equation is equal.
