Which is true of the reactants in this displacement reaction? fe + 2hcl fecl2 + h2a. the reactants are located to the left of the arrow in the chemical equationb. the reactants contain 1 iron atom, 2 hydrogen atoms, and 1 chlorine atom. c. the reactants are the atoms, molecules, or compounds formed in the reaction. d. the reactants have the same physical and chemical properties as the products.

Option (A) is the correct answer.

Explanation:

A displacement reaction is defined as a reaction in which an element reacts with a compound and an element of the compound is displaced by another element.

For example,

In this reaction, there are one Fe atom, 2 hydrogen and 2 chlorine atoms on the reactant side.

Since, it is a chemical reaction therefore, properties of both reactants and products will be different.

Species present on the left side of arrow are reactants and on the right side of arrow depicts products.

Thus, we can conclude that the statement reactants are located to the left of the arrow in the chemical equation, is true.
