Homework Answers
3)a) Single displacement reaction because Cu displace H+ and redox reaction because Cu get oxidized and N get reduced.
b) Single displacement and redox. Because Mg disppdis H+ and Mg get Oxidized whereas H get reduced.
c) Double displacement reaction. Because Cu displace H and Cl displace O.
d) Precipitation. Because Cu(OH)2 precipitate out.
e) Single displacement and redox because Mg displace Cu and Mg get oxidized whereas Cu get reduced.
