Chemical reactions in aqueous solution that involve ionic reactants or products may be represented more realistically by complete ionic equations and, more succinctly, by net ionic equations. Balanced equations are those whose coefficients result in equal numbers of atoms for each element in the reactants and products. Question: What kinds of evidence indicate a chemical change has taken place? equation: Left side: H _____ O _____ Right side: H _____ O _____. Lesson 2 Outline (Matter and its changes) DRAFT. Double replacement : Two compounds react to form two different compounds. The amount of product generated by a chemical reaction is its actual yield. In an exothermic reaction, the reactants contain more energy than the products. Decomposition : One reactant breaks down to form two or more products. The only sure sign that a chemical change occurred is when a new _________________form.
