Answer: A.) Cl₂ + 2KI → 2KCl + I₂
Explanation: This reaction is balanced.
Cl₂ + 2KI → 2KCl + I₂ needed to balance the reaction. The correct option is A.
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total oxidation numbers is the same for both the reactants and the products.
To adjust the substance condition, you need to ensure the number of molecules of every component on the reactant side is equivalent to the number of particles of every component on the item side. To make the two sides equivalent, you should duplicate the number of particles in every component until the two sides are equivalent.
Hence, Cl₂ + 2KI → 2KCl + I₂ is needed to balance the reaction.
