Small samples of oxygen gas needed in the laboratory can be generated by a number of simple chemical reactions. One such reaction is the decomposition of potassium chlorite: 2 KClO3 (s)---> 2 KCl (s) + 3 O2 (g)  According to this balanced chemical equation, how many moles of oxygen has are produced when 2 moles of KClO3 react? How many moles of KCl are also produced? If only 1 mole of KClO3 was reacted, how many moles of O2 would produced? If 4 moles of KClO3 were reacted, how many moles of O2 would be produced?

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".
