Final answer:
The products of the double replacement reaction between Zn(NO3)2(aq) and K2CO3(aq) are ZnCO3(s) and KNO3(aq), with ZnCO3 precipitating as a solid and KNO3 remaining in the aqueous phase.
Step-by-step explanation:
The student is asking about the products formed in a double replacement reaction between Zn(NO3)2(aq) and K2CO3(aq). In a double replacement reaction, the cations and anions of the reactants switch partners. The correct products for this reaction would be ZnCO3 and KNO3. However, a solubility check will show that while KNO3 is soluble in water and remains in the aqueous phase, ZnCO3 is insoluble and will precipitate out of the solution.
Here is the balanced equation for the reaction
Zn(NO3)2(aq) + K2CO3(aq) → ZnCO3(s) + 2KNO3(aq)
