Question

Use your knowledge about solubility rules and reactions to write (1) a balanced chemical
equation (molecular equation), (2) a total ionic equation, and (3) a net ionic equation for the
reactions below. Include the appropriate phase for each species. Do your experimental
observations match your predictions? Write neatly!

(d) (NH4)2SO4(aq) + SrCl2(aq) →

(e) (NH4)2SO4(aq) + H2SO4(aq) →

(g) Mg(NO3)2(aq) + Na2CO3(aq) →

(h) Mg(NO3)2(aq) + SrCl2(aq) →

(I) Mg(NO3)2(aq) + H2SO4(aq) →

13
(j) NaOH(aq) + Na2CO3(aq) →

Answer 1

d)

Molecular equation
(NH₄)2SO₄(aq) + SrCl₂(aq) --------------> 2 NH₄Cl(aq) + SrSO₄(s)
Ionic equation
2NH₄⁺(aq) + SO₄^2- (aq) + Sr²⁺(aq) + 2Cl^- (aq) --- > SrSO₄ (s) + 2 NH₄⁺(aq) + 2 Cl^-(aq)  
Net ionic equaion
SO₄^2- (aq) + Sr²⁺ (aq) --- > Sr₂ SO₄ (s)

e) (NH₄)₂SO₄(aq) + H₂SO₄(aq) --------------> no reaction

because (NH4)2SO4(aq) and H2SO4 are acidic. so tht noth do not involves in reaction.

g) Mg(NO₃)₂(aq) + Na₂CO₃ (aq) ----> MgCO₃ (s) + 2 NaNO₃(aq)

Total ionic reaction –

Mg²⁺(aq) + 2 NO₃^-(aq) + 2 Na⁺(aq) + CO₃^2-(aq) + ----> MgCO₃ (s) + 2 Na⁺(aq) + 2 NO₃^-(aq)

Net ionic reaction –

Mg²⁺(aq) + CO₃^2-(aq) ----> MgCO₃ (s).

`h) Mg(NO₃)₂(aq) + SrCl₂(aq) ------> MgCl₂ (aq) + Sr(NO₃)₂ (aq)

Total ionic reaction –

Mg²⁺(aq) + 2 NO₃^-(aq) + Sr²⁺(aq) + 2Cl^-(aq) + ----> Mg²⁺(aq) +2Cl^-(aq) + 2 Sr²⁺(aq) + 2 NO₃^-(aq)

Net ionic reaction –

No net ionic reaction

I) Mg(NO₃)₂(aq) + H₂SO₄(aq) -----> 2 HNO₃(aq) + MgSO₄(aq)

Total ionic reaction –

Mg²⁺(aq) + 2 NO₃^-(aq) + 2 H⁺(aq) + SO₄^2-(aq) + ---->2 H⁺(aq) + 2 NO₃^-(aq) + Mg²⁺(aq) + SO₄^2-(aq)

Net ionic reaction –

No net ion reaction

J) NaOH (aq) + Na2CO3 (aq) --> There is no reaction that takes place. both reactants are base. so, d not participate in reaction.

hey, if you find nay doubt please ask and please give thumb up. thanks
