Writing chemical equations

Chemical equations Writing a skeleton equation is an important step toward using an equation to completely describe a chemical reaction. But, like word equations, skeleton equations also lack important information about reactions. Recall from Chapter 3 that the law of conservation of mass states that in a chemical change, matter is neither created nor destroyed. Chemical equations must show that matter is conserved during a reaction, and skeleton equations lack that information. [Pg.280]

A chemical reaction occurs when the atoms in substances rearrange and combine into new substances. We represent a reaction by a chemical equation, writing a chemical formula for each reactant and product. The coefficients in the equation indicate the relative numbers of reactant and product molecules or formula units. Once the reactants and products and their formulas have been determined by experiment, we determine the coefficients by balancing the numbers of each kind of atom on both sides of the equation.
