Balanced equations given below,
a. As2S5 + 40NO3- + 35H+ --> 2H3AsO4 + 5HSO4- + 40NO2 + 12H2O
c. 4CrO4^2-(aq) + 22H+(aq) + 3Cl-(aq) --> 4Cr3+(aq) + 3ClO2-(aq) + 10H2O(l)
d. IO3-(aq) + 2Cr(OH)4-(aq) + 2OH-(aq) --> 2CrO4^2-(aq) + I-(aq) + 5H2O(l)
e. 5Fe(CN)6^4- + 61MnO4- + 188H+ --> 5Fe3+ + 30CO2 + 30NO3- + 61Mn2+ + 94H2O
f. 2CoCl2(s) + Na2O2(aq) + 2H2O(l) + 2NaOH(aq) --> 2CO(OH)3(aq) + 4Na+(aq) + 4Cl-(aq)
g. 2MnO4-(aq) + 5C2O4^2-(aq) + 16H+(aq) --> 2Mn2+(aq) + 10CO2(aq) + 8H2O(l)
h. Hg2(CN)2 + 22Ce4+ + 28OH- --> 2CO3^2- + 2NO3- + 2Hg(OH)2 + 22Ce3+ + 12H2O
i. 2MnO4-(aq) + 2Sb + 2H+(aq) --> 2MnO2(s) + Sb2O3(s) + H2O(l)
