Step-by-step explanation:
Here, we want to get the product from the double displacement reaction
A double displacement reaction also known as a double decomposition reaction involves the exchange of anions between the metallic elements to produce a solid precipitate and an aqueous solution alongside
We have the equation of reaction as follows:
![MgCl_(2(aq))\text{ + Na}_2CO_(3(aq))\text{ }\rightarrow\text{ 2NaCl}_((aq))\text{ + MgCO}_(3(s))](https://img.qammunity.org/2023/formulas/chemistry/college/x7sbj6p3xaje9v67u2t409r49675gb798f.png)
