Worksheet #2 DECOMPOSITION REACTIONS RULESIF THE REACTANT IS A SINGLE COMPOUND, THE REACTION IS A DECOMPOSITION REACTION. GENERAL EQUATION: AB A + B [ Compound Element1 + Element2 ] APPLY THESE RULES TO DECOMPOSTION REACTIONS: salt metal + nonmetal ternary acid nonmetal oxide (acid anhydride) + water metal hydroxide metal oxide (basic anhydride) + water metal chlorate metal chloride + oxygen salt (with polyatomic ion) nonmetal oxide + metal oxide metal carbonate metal oxide + carbon dioxide metal oxide metal + oxygen hydrated salts anhydrous salt + water STATES OF MATTER IN DECOMPOSITION REACTIONS: nonmetal oxides (g) metal oxides (s) salts (s) water as a product (g) water as a reactant (l) acids (aq) individual elements (look at periodic chart for state) THE DIATOMICS: H2, N2, O2, F2, Cl2, Br2, I2 DIRECTIONS: Determine the products of each reaction. Balance the equation. Indicate the states of matter on all reactants and products. Place the rule number for each to the right of each problem.
