Chemistry 51 ASNWER KEY. REVIEW QUESTIONS . Chapter 6. 1. Classify the type of each of the following reactions: a) (NH4)2SO4 2 NH3 + SO2 + H2 decomposition b) Br2 + 2 KI 2 KBr + I2 single replacement c) 2 Na + Cl2 2 NaCl synthesis d) Al(OH)3 + 3 HCl AlCl3 + 3 H2O double replacement 2. Balance each of the equations shown below: a) 5 C + 2 SO2 1 CS2 + 4 CO. b) 2 Na3N 6 Na + 1 N2. c) 1 C3H8 + 5 O2 3 CO2 + 4 H2O. d) 2 Al + 3 H2SO4 1 Al2(SO4)3 + 3 H2. 3. Predict the products for each reaction and balance the equation. If no reaction occurs, write No Reaction after the arrow: a) 2 Al (s) + 6 HCl (aq) 2 AlCl3 (aq) + 3 H2 (g). b) 3 Mg (s) + 2 FeCl3 (aq) 3 MgCl2 (aq) + 2 Fe (s). c) 1 F2 (g) + 2 KCl (aq) 2 KF (aq) + Cl2 (g). d) Cu (s) + Ca(NO3)2 No Reaction (Ca is more reactive than Cu). e) 1 Pb (s) + 2 AgNO3 (aq) Pb(NO3)2 (aq) + 2 Ag (s). 1. 4.
