44) Balance the following equations by oxidation number method

i) K2Cr207+ KI + H2SO4 → K2SO4 + Cr2(SO4)3 +12+H2O

 \sf \: K_2Cr_20_7 +  KI + H_2SO_4 →  K_2SO_4 + Cr_2(SO_4)_3 +  H_2

ii) KMnO4 + Na S03 → MnO2 + Na SO4 + KOH

 \sf\: KMnO_4 + NaSO_3 →  MnO_2 +  NaSO_4 +  KOH

iii) Cu+ HNO3 → Cu(NO3)2 + NO2 + H2

 \sf \: Cu (s) + 4 HNO_3 (aq) → Cu(NO_3)_2 (aq) + 2 NO_2 (l) + 2 H_2O (l)

iv) KMnO4+H2C2O4 + H2SO4 → K2SO4 + MnSO4 + CO2 + H2O

 \sf \: 2 KMnO_4 + 9 H_2C_2O_4 + 3 H_2SO_4 → K_2SO_4 + 2 MnSO_4 + 18 CO_2 + 8 HH_2O
