Question

(iii) (NH4)2 Cr2O + Cr2O3 + H2O + N2
plz balance this reaction
​

Answer 1

Answer:

(NH4)2Cr2O7 → H2O + N2 + Cr2O3

2 (NH4)2Cr2O7 → H2O + O2 + NH3 + Cr2O3

3 H2SO4 + KI + (NH4)2Cr2O7 → H2O + K2SO4 + I2 + Cr2(SO4)3 + (NH4)SO4

4 H2SO4 + KI + (NH4)2Cr2O7 → H2O + K2SO4 + I2 + Cr2(SO4)3 + (NH4)2SO4

5 H2SO4 + (NH4)2Cr2O7 + NH4I → H2O + I2 + Cr2(SO4)3 + (NH4)2SO4
