The products for the following: CaCl2(aq) + K2CO3(aq) �¨
A. CaCO3(s) + 2KCl(aq)
B. CaCO3(aq) + 2KCl(s)
C. none of these
D. no reaction
the answer is option A
To determine the products of the chemical reaction between CaCl2(aq) and K2CO3(aq), we need to identify the ions present in the aqueous solutions and use the principles of chemical reactions.
CaCl2(aq) contains the ions Ca^2+ and Cl^-.
K2CO3(aq) contains the ions K^+ and CO3^2-.
When these solutions are mixed, a double replacement reaction occurs, where the positive ions (cations) switch places and form new compounds with the negative ions (anions).
The cation Ca^2+ from CaCl2 will combine with the anion CO3^2- from K2CO3 to form CaCO3. The anion Cl^- from CaCl2 will combine with the cation K^+ from K2CO3 to form KCl.
Therefore, the correct answer is:
A. CaCO3(s) + 2KCl(aq)
To determine the products of the reaction between CaCl2(aq) and K2CO3(aq), we need to identify the ions present in each compound and then combine them to form new compounds.
CaCl2 is made up of the calcium ion (Ca2+) and two chloride ions (Cl-). K2CO3 contains two potassium ions (K+) and one carbonate ion (CO32-).
When these compounds react, the positive and negative ions will combine. The calcium ion, Ca2+, will combine with the carbonate ion, CO32-, to form CaCO3. The two potassium ions, K+, will combine with the chloride ions, Cl-, to form 2KCl.
Therefore, the correct answer is A. CaCO3(s) + 2KCl(aq).
