Answer:
[tex]D\text{ : NaCl}_{(aq)\text{ }}and\text{ MgCO}_{3(s)}[/tex]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:
[tex]MgCl_{2(aq)}\text{ + Na}_2CO_{3(aq)}\text{ }\rightarrow\text{ 2NaCl}_{(aq)}\text{ + MgCO}_{3(s)}[/tex]
