The only reactant in this decomposition reaction is potassium chlorate, KClO3. The manganese(IV) oxide is just a catalyst; it gets the reaction going but does not react. The gaseous product causes the glowing wood, paper or tobacco to combust, just like the methane in its combustion reaction in A2. What is the gaseous product of this decomposition reaction?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
