A key step in balancing chemical equations is correctly identifyingthe formulas of the reactants and products. For example,consider the reaction between calcium oxide, CaO(s),and H2O(l) to form aqueous calcium hydroxide. (a) Write abalanced chemical equation for this combination reaction,having correctly identified the product as Ca(OH)2(aq).(b) Is it possible to balance the equation if you incorrectly identifythe product as CaOH(aq), and if so, what is the equation?

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".
