WebThe stoichiometry. of a reaction is the ratio of the amounts of each substance in the balanced equation. It can be deduced or worked out using masses found by experiment. Example. 6.0 g of magnesium reacts with 4.0 g oxygen to produce magnesium oxide, MgO. Deduce the balanced equation for the reaction. (A r of Mg = 24, M r of O 2 = 32) WebNo atoms are created or destroyed in a chemical reaction.
