12. Solid ammonium carbonate, (NH4)2CO3, is used as the active ingredient in "smelling salts." When solid ammonium carbonate is heated, it decomposes into am- monia gas, carbon dioxide gas, and water vapor. Write the unbalanced chemical equation for this process. 13. Silver oxide may be decomposed by strong heating into silver metal and oxygen gas. Write the unbal- anced chemical equation for this process. 14. Methanol (CH3OH, wood alcohol) is an important in- dustrial chemical. Methanol may be synthesized from carbon monoxide gas and hydrogen gas under certain conditions of temperature and pressure. Write the un- balanced chemical equation for this process. 15. Elemental boron is produced in one industrial process by heating diboron trioxide with magnesium metal, also producing magnesium oxide. Write the unbal- anced chemical equation for this process. 16. Calcium metal is moderately reactive. If pieces of cal- cium are added to water, the metal begins to bubble as hydrogen gas is formed. The water begins to turn cloudy, as solid calcium hydroxide begins to form. Write the unbalanced chemical equation for the re- action of calcium metal with water.
