If Solutions of Potassium Chromate and Sodium Nitrate Are Mixed

Multiple Choice

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

A) Yes. K₂CrO₄(aq) + NaNO₃(aq) → KNO₃(aq) + NaCrO₄(s)
B) Yes. K₂CrO₄(aq) + NaNO₃(aq) → KNO₃(aq) + CaK(s)
C) No reaction will occur.
D) Yes. K₂CrO₄(aq) + NaNO₃(aq) → 2KNO₃(aq) + NaaCrO₄(s)
E) Yes. K₂CrO₄(aq) + NaNO₃(aq) → K₂(NO₃) ₂(aq) + Na₂CrO₄(s)
