Nature of Reactants and Products

Reactants

Metal + lonic compound

Products

Metal + lonic compound

Which of the following is true about the type of chemical reaction?

it is a single replacement reaction, and the anions in the two inic compounds are different.

It is a single replacement reaction, and the cations in the two ionic compounds are different.

It is a double replacement reaction, and the anions in the two ionic compounds are different.

It is a double replacement reaction, and the cations in the two ionic compounds are different.

Answer 1

Answer: It is true about the type of reaction that it is a single replacement reaction, and the cations in the two ionic compounds are different.

Explanation:

When one element in a compound is replaced by another element in a chemical reaction then it is called a single replacement reaction.

For example, $K + NaCl \rightarrow KCl + Na$

Here, potassium metal is replacing the sodium metal in the sodium chloride compound.

As metals become cation by losing an electron in a chemical reaction.

Thus, we can conclude that it is true about the type of reaction that it is a single replacement reaction, and the cations in the two ionic compounds are different.
