Balancing Chemical Equations Practice 1 Answer Key. 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. Question Represent each of the following word equations with a balanced chemical equation. a)Disilane gas (Si 2 H 6) undergoes combustion to form solid silicon dioxide and water. b)Solid aluminum hydride is formed by a combination reaction of its two elements. Balancing equation exercise. Balancing chemical equations exercise. Chemical equations are the written or symbolic representation of a chemical reaction. Balancing these chemical equations, through the application of stoichiometry concepts, is an essential skill that almost all students will learn starting sometime around the 8th year of school.
