A double replacement reaction, also known as a double displacement reaction, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds. The general formula for a double replacement reaction is , where and are cations, and and are anions. In this reaction, and are the cations of the two new compounds, and D\) are the anions of the new compounds.Option A, , represents a synthesis reaction, where two or more simple substances combine to form a more complex compound.Option B, , represents a decomposition reaction, where a single compound breaks down into two or more simpler substances.Option C, , represents a single replacement reaction, where one element trades places with another element in a compound.Option D, , correctly represents a double replacement reaction, where the cations and anions of the two reactants switch places, forming two new compounds.Therefore, the correct answer is option D.
