Balance each of the following in BASE:
a) CN-+ MnO4-®CNO-+
MnO2(hint:  treat CN as a UNIT with a single
oxidation number…this shortcut will not show you which of C or N is
being oxidized or reduced, but it will show you whether
oneof them is being oxidized or reduced, which
will give you the info you need. This is harder than something I’d
put on the exam).
b) Mn2++ H2O2®MnO2+
H2O (hint:  H2O2has
oxygen in the RARE -1 oxidation state. One more of these outliers,
just for practice.)
c) Bi(OH)3+
SnO22-®SnO32-+ Bi
d) CrO42-(aq)+
Cu(s)®Cr(OH)3(s)+ Cu(OH)2(s)
