Question

Пожалуйста срочно нужен ответ, помогите люди кто нибудь. Составьте молекулярные и ионно - молекулярные уравнения реакций, протекающие при смешивании растворов: а) Ba(OH)2 и K₂SO4б) Mg(OH)2 и H2SO4​

Answer 1

Объяснение:

а) Ba(OH)2 + K₂SO4 = BaSO4↓ + 2KOH

Ba²+ + 2OH- + 2K+ + SO4²- = BaSO4↓ + 2K+ + 2OH-

Ba²+ + SO4²- = BaSO4↓

б) Mg(OH)2 + H2SO4 = MgSO4 + 2H2O

Mg²+ + 2OH- + 2H+ + SO4²- = Mg²+ + SO4²- + 2H2O

H+ + OH- = H2O

Answer 2

Molecular and Ionic-Molecular Equations for the Given Reactions

a) When Ba(OH)2 and K2SO4 are mixed, they react to form BaSO4 and 2KOH.

The molecular equation for this reaction is: Ba(OH)2 + K2SO4 -> BaSO4 + 2KOH

The ionic equation for this reaction is: Ba^2+ + 2OH^- + 2K^+ + SO4^2- -> BaSO4 + 2K^+ + 2OH^-

b) When Mg(OH)2 and H2SO4 are mixed, they react to form MgSO4 and 2H2O.

The molecular equation for this reaction is: Mg(OH)2 + H2SO4 -> MgSO4 + 2H2O

The ionic equation for this reaction is: Mg^2+ + 2OH^- + 2H^+ + SO4^2- -> MgSO4 + 2H2O

Please note that these equations represent the balanced chemical reactions that occur when the given solutions are mixed.
