Will there be a precipitate for the following reaction? Aqueous zinc chloride + aqueous sodium carbonate A. No B. Yes, there will be one precipitate. C. Yes, there will be two precipitates. D. Yes, there will be three precipitates.

Option B. Yes, there will be one precipitate.

Explanation:

We'll begin by writing the balanced equation for the reaction between aqueous zinc chloride and aqueous sodium carbonate. This is given below:

ZnCl2(aq) + Na2CO3(aq) —> ZnCO3(s) + 2NaCl(aq)

From the equation above, we can see that one precipitate is form i.e zinc carbonate, ZnCO3 as it is insoluble in water.

Therefore, the reaction produces one precipitate.
