Question

Complete and balance the precipitation reaction. include physical states in your answer. click here for solubility rules. cucl2 (aq) + na2co3 (aq) --->

Answer 1

Answer:

The balanced chemical reaction is - $CuCl_{2}(aq.)+Na_{2}CO_{3}(aq.)\rightarrow CuCO_{3}(s)+2 NaCl(aq.)$

Explanation:

According to solubility rule, $CuCO_{3}$ is an insoluble compound and NaCl is a water soluble compound.

The given precipitation reaction involves exchange of cations and anions between $CuCl_{2}and Na_{2}CO_{3}$, resulting formation of insoluble $CuCO_{3}$ and NaCl.

Balanced equation:  $CuCl_{2}(aq.)+Na_{2}CO_{3}(aq.)\rightarrow CuCO_{3}(s)+2 NaCl(aq.)$

Answer 2

Hey there!:

Balanced equation:

Na2CO3(aq) + CuCl(aq) -> CuCO3(s) + 2 NaCl(aq)  

Since CuCO3 is more stable so displacement and precipitation will take place.

Hope that helps!
