When an aqueous solution of magnesium nitrate is mixed with an aqueous solution of potassium carbonate, ) kno3 will precipitateb) mgco3 will precipitatec) both mgco3 and kno3 will precipitated) no reaction occurs

The correct answer is Option B.

Explanation:

Double displacement reaction is defined as the chemical reaction in which exchange of ions takes place.

An insoluble salt in a solution is termed as a precipitate.

When an aqueous solution of magnesium nitrate reacts with an aqueous solution of potassium carbonate, it leads to the formation of an aqueous solution of potassium nitrate and a solid precipitate of magnesium carbonate.

The chemical equation for the above reaction follows:

Hence, the correct answer is Option B.
