(a)Two of the reactions in the “Copper Cycle” are classified as oxidation-reduction (“’redox”) reactions. Identify the two reactions, and identify the oxidizing agent and the reducing agent in each.
(b)Which one of the redox reactions above can be classified as a single displacement reaction?
(c)One of the reactions in this experiment is classified as a decomposition reaction. Identify it:
(d)One of the reactions in this experiment is classified as a precipitation reaction. Identify it:
(e)One of the reactions in this experiment is classified as an acid-base reaction. Identify it:
a)
the two redox reactions are
Cu + 4 HN03 ---> Cu(N03)2 + N02 + H20
oxidizing agent --> HN03
reducing agent --> Cu
Zn + CuS04 -> Cu + ZnS04
oxidizing agent --> Cu
reducing agent --> Zn
b) single displacement reaction is
Zn + CuS04 ---> Cu + ZnSO4
c) the decomposition reaction is
Cu(OH)2 + heat ---> CuO + H20
d) the precipitation reaction is
Cu(N03)2 + 2 NaOH --> Cu(OH)2 (s) + 2 NaN03
here
Cu(OH)2 is the precipitate in this case
e) the acid base reaction is
HN03 + NaOH ---> NaN03 + H20
