Abstract: Balancing equations in chemical reactions is very basic and fundamental concept and in some cases it becomes more difficult so that a mathematical treatment is needed in order to make it easy. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. The idea rests on establishing a system of simultaneous homogenous linear equations for the given chemical equation. This paper proposes and illustrates a simple mathematical technique for balancing chemical equations. It is necessary to balance it because there must be equal number of atoms on both the sides of the equation. c) The type and number of atoms must balance on both sides of the chemical equation. Replace immutable groups in compounds to avoid ambiguity. (2010). BALANCING(CHEMICAL(EQUATIONS( 2 8. Hence, this method is called the hit and trial method.
