Answer #1

MnO4-(aq)+S2(aq)--->MnS(s)+S(s)

split reactions

MnO4- = MnS

S-2 = S

balance O

MnO4- = MnS + 4H2O

S-2 = S

balance H

8H+ + MnO4- = MnS + 4H2O

S-2 = S

balance charges

7e- + 8H+ + MnO4- = MnS + 4H2O

S-2 = S + 2e-

balance e-

14e- + 16H+ + 2MnO4- = 2MnS + 8H2O

7S-2 = 7S + 14e-

add all

14e- + 16H+ + 2MnO4- + 7S-2= 2MnS + 8H2O +  7S + 14e-

cancel common terms

16H+ + 2MnO4- + 7S-2= 2MnS + 8H2O +  7S

add OH-

16OH- + 16H+ + 2MnO4- + 7S-2= 2MnS + 8H2O +  7S +16OH-

cancel H+ and OH-

16H2O + 2MnO4- + 7S-2= 2MnS + 8H2O +  7S +16OH-

cancle waters

8H2O + 2MnO4- + 7S-2= 2MnS +  7S +16OH-
