![]() Count the number of H and O atoms on both sides.Process: Start with the most complex molecule or the one with the most elements, and adjust the coefficients of the reactants and products until the equation is balanced. It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation.īest for: Simple equations with a small number of atoms. Balancing with inspection or trial and error method A balanced equation obeys the Law of Conservation of Mass, which states that matter is neither created nor destroyed in a chemical reaction. However, this equation isn't balanced because the number of atoms for each element is not the same on both sides of the equation. For example, in the reaction of hydrogen (H₂) with oxygen (O₂) to form water (H₂O), the chemical equation is: It shows the reactants (substances that start a reaction) and products (substances formed by the reaction). ![]() calcium hydroxide + carbon dioxide = calcium carbonate + waterĮxamples of the chemical equations reagents (a complete equation will be suggested):Ī chemical equation represents a chemical reaction.PhCH 3 + KMnO 4 + H 2SO 4 = PhCOOH + K 2SO 4 + MnSO 4 + H 2O.To enter an electron into a chemical equation use + H 2O.Compare: Co - cobalt and CO - carbon monoxide ![]()
