Question

(NH4)2SO4+Ba(NO3)2--> (NH4)2SO4+NaOH-------> Написать молекулярные и ионные уравнения соответствующих реакций.

Answer 1

(NH4)2SO4+NaOH------->NH3OH+Na2So4

Answer 2

Molecular equation:

(NH4)2SO4 + Ba(NO3)2 → BaSO4 + 2NH4NO3

Ionic equation:

2NH4+ (aq) + SO4^2- (aq) + Ba^2+ (aq) + 2NO3- (aq) → BaSO4 (s) + 2NH4+ (aq) + 2NO3- (aq)

Net ionic equation:

SO4^2- (aq) + Ba^2+ (aq) → BaSO4 (s)

Molecular equation for the second reaction:

(NH4)2SO4 + 2NaOH → 2NH3 (g) + 2H2O (l) + Na2SO4

Ionic equation:

2NH4+ (aq) + SO4^2- (aq) + 2Na+ (aq) + 2OH- (aq) → 2NH3 (g) + 2H2O (l) + 2Na+ (aq) + SO4^2- (aq)

Net ionic equation:

2NH4+ (aq) + 2OH- (aq) → 2NH3 (g) + 2H2O (l)
