Chapter 4: Quantities of Reactants and Products 4.1 Chemical Equations combustion reactions – element or compound burns in air or oxygen; products are CO 2 and water balanced chemical equation – relative amounts of reactants and products required so that number of atoms of each element in reactants and products are same aqueous solution – dissolved in water, indicated by (aq) stoichiometry – relations among masses of chemical reactants and products stoichiometric coefficients – coefficients in balanced equation 4.2 Patterns of Chemical Reactions Combination Reactions o combination reaction – 2 or more substances react to form single product: X + Z XZ o i.e., oxygen and halogens are so reactive that they undergo combination reactions with most elements o metal + oxygen metal oxide (ionic compound) o nonmetals + oxygen/chlorine molecular compounds Decomposition Reactions o decomposition reaction – one substance decomposes to form two or more products: XZ X + Z o many “stable” compounds undergo decomposition when temperature is raised – thermal decomposition o metal carbonates
