. Balance the following equations.
(i) Cu2O + H+ + 
= Cu2+ + NO + H2O
= Cu2+ + NO + H2O (ii) K4[Fe(CN)6] + H2SO4 + H2O = K2SO4 + FeSO4 + (NH4)2SO4 + CO
(iii) C2H5OH + I2 + OH- = CHI3 + 
+ I- + H2O
+ I- + H2O

O 2 + NO + 3H2+= 2Cu-3 + NO+O + 6H2Cu
+ 6CO4SO2)4 + 3(NH4 + FeSO4SO2O = 2K2 + 6H4SO2] + 6H6[Fe(CN)4 K
3rd is a combination of 2 reactions i think .

SORRY
Cu2O+6H++NO3- ---> 2Cu2+ + NO +3H2O
K4[Fe(CN)6] + 6H2SO4 + 6H2O ------> 2K2SO4 +FeSO4+ 3(NH4)2SO4+6CO
3RD ONE IS A COMBINATION OF 2 REACTION. SEND THE REACTIONS GIVEN.(if there)

Balance the reactions by ion electron method.
(i) Cu2O + 2H+ → 2CU2+ + H2O + 2e-] * 3 ….(i)
NO3- + 4H+ + 3e- -> NO + 2H2O] * 2 …..(ii)
3CU2O + 14H+ + 2NO3- -> 6CU2+ + 2NO6 + 7H2O
3CU2O + 14H+ + 2NO3- -> 6CU2+ + 2NO6 + 7H2O
(ii) K4[Fe(CN)6] + 6H2SO4 + 6H2O
→ 2K2SO4 + FeSO4 + 3(NH4)2SO4 + 6CO
(iii) C2H2OH + 4I2 + 8OH-
→CHI3 + HCO3- + 5I- + 6H2O
