Balance each of the following redox reactions occurring in basicsolution.

a)MnO?4(aq)+Br?(aq)?MnO2(s)+BrO?3(aq)

MnO?4(aq)+H2O(l)+Br?(aq)?MnO2(s)+2OH?(aq)+BrO?3(aq)

2MnO?4(aq)+H2O(l)+Br?(aq)?2MnO2(s)+2OH?(aq)+BrO?3(aq)

2MnO?4(aq)+H2O(l)+Br?(aq)?2MnO2(s)+OH?(aq)+BrO?3(aq)

MnO?4(aq)+H2O(l)+2Br?(aq)?MnO2(s)+OH?(aq)+2BrO?3(aq)

b)Ag(s)+CN?(aq)+O2(g)?Ag(CN)?2(aq)

2Ag(s)+4CN?(aq)+2O2+H2O(l)(g)?2Ag(CN)?2(aq)+2OH?(aq)

2Ag(s)+8CN?(aq)+4O2+2H2O(l)(g)?4Ag(CN)?2(aq)+8OH?(aq)

4Ag(s)+2CN?(aq)+O2+4H2O(l)(g)?4Ag(CN)?2(aq)+8OH?(aq)

4Ag(s)+8CN?(aq)+O2+2H2O(l)(g)?4Ag(CN)?2(aq)+4OH?(aq)

c)NO?2(aq)+Al(s)?NH3(g)+AlO?2(aq)

NO?2(aq)+H2O(l)+2Al(s)+OH?(aq)?NH3(g)+2AlO?2(aq)

2NO?2(aq)+H2O(l)+2Al(s)+OH?(aq)?2NH3(g)+2AlO?2(aq)

2NO?2(aq)+H2O(l)+Al(s)+2OH?(aq)?2NH3(g)+AlO?2(aq)

NO?2(aq)+2H2O(l)+Al(s)+2OH?(aq)?NH3(g)+AlO?2(aq)
