PRE-LAB QUESTIONS Complete the following steps for each reaction below: a. Name the type of reaction that is occurring. b. State if the reaction is balanced. c. If the reaction is not balanced, write the complete balanced reaction. • CH 4 (g) + O 2 (g) → CO 2 (g) + H 2 O (g) + Energy Combustion Reaction Not Balanced CH4(g) + 2O2 (g) → CO2 (g) + 2H2O (g) + Energy • N i2 O 3 (s) → Ni (s) + O 2 (g) Decomposition Not Balanced 2Ni2O3 (s) → 4Ni (s)+3O2 (g) • Al (s) + CuSO 4 (aq) → Cu (s) + Al 2 (SO 4 ) 3 (aq) Displacement reaction Not Balanced 2 Al(s) +3CuSo4(aq) → 3Cu(s) + Al2(So4) 3(aq) • Na 2 CO 3 (aq) + HCl (aq) → NaCl (aq) + H 2 CO 3 (aq)
