Question

     For the following reactions, identify the type (combination, combustion, decomposition, displacement, methathesis [double-displacement)] neutralization), balance the reaction, and for the redox reactions identify the oxidizing agent and reducing agent.

            (a)  CH4  +  O2  ?  CO2  +   H2O

            (b)  HCl +  NaOH  ? H2O  +  NaCl

            (c)  H2 +  O2  ?  H2O

            (d)  CaCO3  + HCl  ? CaCl2  +  CO2  +  H2O

            (e)  Zn +  HCl  ?  ZnCl2  +  H2

              (f)   NaCl ? Na + Cl2

Explanation / Answer

a) combustion, CH4  + 2 O2  ?  CO2  + 2H2O

b)neutralization HCl +  NaOH  ? H2O  +  NaCl

c)redox reactions 2H2 +  O2  ? 2 H2O oxidizing agent=02 reducing agent=H2

D)decomposition CaCO3  +2HCl  ? CaCl2  +  CO2  +  H2O

E) displacement Zn + 2 HCl  ?  ZnCl2  +  H2

F)decomposition 2NaCl ? 2Na+ + Cl2
