a. Molecular equation: AgNO₃(aq) + NaI(aq) > NaNO₃(aq) + AgI(s)
Net ionic equation: Ag⁺(aq) + I⁻ ---> AgI(s)
b. Molecular equation: Ba(NO₃)₂(aq) + K₂SO₄(aq) > 2KNO₃(aq) + BaSO₄(s)
Net ionic equation: Ba²⁺(aq) + SO₄²⁻(aq) ---> BaSO₄(s)
c. Mg(NO₃)₂ + K₂SO₄ > No reaction
d. CaCl₂ + AI(NO₃)₃ > No reaction
Note: The question is incomplete. A complete similar question is given below:
Write the molecular equation and the net ionic equation for each of the following aqueous reactions. If a reaction is not carried out, write NR after the arrow.
a. AgNO₃ + NaI⁻
b. Ba(NO₃)₂ + K₂SO₄
c. Mg(NO₃)₂ + K₂SO₄
d. CaCl₂ + AI(NO₃)₃
Explanation:
a. A double displacement reaction occur between aqueous solutions of silver nitrate and sodium iodide to give a precipitate of silver iodide.
Molecular equation: AgNO₃(aq) + NaI(aq) > NaNO₃(aq) + AgI(s)
Net ionic equation: Ag⁺(aq) + I⁻ ---> AgI(s)
b. A double displacement reaction occurs between aqueous solutions of barium nitrate and potassium sulfate to produce a precipitate of barium sulfate
Molecular equation: Ba(NO₃)₂(aq) + K₂SO₄(aq) > 2KNO₃(aq) + BaSO₄(s)
Net ionic equation: Ba²⁺(aq) + SO₄²⁻(aq) ---> BaSO₄(s)
c. Since no precipitate is formed when aqueous solutions of magnesium nitrate and potassium sulfate are mixed together, no reaction occurs
Mg(NO₃)₂ + K₂SO₄ > No reaction
d. Since no precipitate is formed when aqueous solutions of calcium chloride and aluminum nitrate are mixed together, no reaction occurs
CaCl₂ + AI(NO₃)₃ > No reaction
