question 25

Multiple Choice

If solutions of potassium carbonate and calcium nitrate are mixed, will a double-displacement reaction occur? If so, what is the balanced equation for the reaction?

• A)Yes. K₂CO₃(aq)+ Ca(NO₃)₂(aq)→ KNO₃(aq)+ CaK(s)
• B)No reaction will occur.
• C)Yes. K₂CO₃(aq)+ Ca(NO₃)₂(aq)→ KNO₃(aq)+ CaCO₃(s)
• D)Yes. K₂CO₃(aq)+ Ca(NO₃)₂(aq)→ K₂(NO₃)₂(aq)+ CaCO₃(s)
• E)Yes. K₂CO₃(aq)+ Ca(NO₃)₂(aq)→ 2KNO₃(aq)+ CaCO₃(s)
