(NH4)2CO3->2NH3+H2O+CO2Decomposition: Ammonium carbonate decomposes into ammonia, water, and carbon dioxide.
H2SO3->H2O+SO2Decomposition: Sulfurous acid decomposes into sulfur dioxide and water.
H2CO3->H2O+CO2Decomposition: Carbonic acid decomposes into carbon dioxide and water.
2NaCl->2Na+Cl2Decomposition: A binary compound may break down to produce two elements.
2H2O2->2H2O+O2Decomposition:Hydrogen peroxide decomposes into water and oxygen.

Section 2

Question Answer
6Li+N2->2Li3NSynthesis: A metal combines with a nonmetal to form a binary salt.
Na2O+H2O->NaOH and MgO+H2O->Mg(OH)2Synthesis: Metallic oxides and water form bases (metallic hydroxides).
CO2+H20->H2CO3 (Oxidation # of C is +4) N2O5+H2O->2HNO3 (Oxidation # of N is +5)Synthesis: Nonmetallic oxides and water form acids. The nonmetal retains its oxidation number.
Na2O+CO2->Na2CO3 and CaO+SO3->CaSO4Synthesis: Metallic oxides and nonmetallic oxides form salts.
