Balancing Chemical Reactions Chemical reactions are like recipes in that the quantity and types of ingredients, or reactants, can be related to the quantity and type of cooked food, or product(s) formed. Balancing chemical reactions then allows one to determine stoichiometry calculations by understanding the ratio between reactants and/or products.

Balancing REDOX Reactions: Learn and Practice Reduction-Oxidation reactions (or REDOX reactions) occur when the chemical species involved in the reactions gain and lose electrons. Oxidation and reduction occur simultaneously in order to conserve charge. We can “see” these changes if we assign oxidation numbers to the reactants and products.

This paper explores an alternative way to balancing equations of chemical reactions and understanding why it is necessary to use balanced equations in science. To balance a chemical equation chemists often guess the coefficients that would balance the equation and check if it works. An alternative method is to
