Smelling salts, which are used to revive someone who has fainted, typically contain ammonium carbonate, (NH4)2CO3. Ammonium carbonate decomposes readily to form ammonia, carbon dioxide, and water. The strong odor of the ammonia usually restores consciousness in the person who has fainted. The unbalanced equation is (NH4)2CO3(s) S NH3(g) _ CO2(g) _ H2O(g) Calculate the mass of ammonia gas that is produced if 1.25 g of ammonium carbonate decomposes completely.
CHAPTER 14 Factors that Influence Reactivity Chemical kinetics o the study of reaction mechanisms and the rates of chemical reactions under various conditions For a reaction to occur to an appreciable amount, it must be both thermodynamically and kinetically favored o Thermodynamic controls the enthalpy change for the reaction the entropy change for the reaction the temperature at which the reaction takes place o kinetic controls the manner in which the reaction takes place (its mechanism) the energy barrier that must be overcome to convert reactants to products (the acti
