Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products. This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation. Two quick and easy methods of balancing a chemical equation are discussed in this article. The first method is the traditional balancing ... Taking a dive into the world of chemical equations? These problems can seem tricky at a glance, but they're easy to figure out once you learn the basic steps and rules to balancing them. Not to worry; we'll walk you through exactly how to... Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below. Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide. Figure 7 3 1: Balancing Equations. You cannot change subscripts in a chemical formula to balance a chemical equation; you can change only the coefficients. Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties. For example, water (H 2 O) and hydrogen peroxide (H 2 O 2) are chemically distinct ...
