Question

Answer all of them...

Interpretation of Reactions by Ionic Type Equations. Aqueous solutions of the following substances
or their mixtures with water if they are only slightly soluble, are mixed. Write first the
conventional equation, second the total ionic equation, and lastly the net ionic equation. If you
predict no appreciable reaction, indicate this, and state why.

a. Magnesium chloride and sodium carbonate

b. Aqueous ammonia and hydrofluoric acid

c. Nitric acid and magnesium acetate

d. Ammonium chloride and sodium hydroxide

e. Barium chloride and calcium nitrate

f. Potassium hydrogen carbonate and sulfuric acid

g. Aluminum hydroxide and nitric acid

h. Aqueous ammonia and sulfuric acid

i. Magnesium nitrate and zinc chloride

Answer 1

a.

MgCl2(aq) + Na2CO3(aq)      MgCO3(s) + 2NaCl(aq)

Ionic equation:

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

Net ionic equation:

Mg²⁺(aq) CO3^2-(aq) MgCO3(s)

b.

HF(aq) + NH3(aq) NH4⁺ (aq) + F^-(aq)

Ionic equation:

H⁺(aq) +  F^-(aq) + NH3(aq)    NH4⁺ (aq) + F^-​(aq)

Net ionic equation:

H⁺(aq) +  F^-(aq) + NH3(aq)      NH4⁺ (aq) + F^-​(aq)

c.

2HNO3(aq) + Mg(C2H3O2)2(aq) Mg(NO3)2(aq) + 2HC2H3O2(aq)

Ionic equation:

2H⁺(aq) + 2NO3^-(aq) + Mg⁺(aq) + 2C₂H₃O₂^-(aq)      Mg⁺(aq) + 2NO3^-(aq) +   2HC2H3O2(aq)

Net ionic equation:

2H⁺(aq) +    2C₂H₃O₂^-(aq)       2HC2H3O2(aq)

d.

NH4Cl (aq) + NaOH (aq) NH4OH (aq) + NaCl (aq)
OR
NH4Cl (aq) + NaOH (aq) NaCl (aq) + H2O (l)+ NH3 (g)

Ionic equation:

NH4⁺ + Cl^- + Na⁺ + OH^-    Na⁺ +   Cl^- +   H2O (l) + NH3 (g)

Net ionic equation:

NH4⁺ + OH^- H2O (l) + NH3 (g)
