question 82

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