Question

Balancing the following chemical reactions by identifying the products.

Fe₃O₄ $+$+HCl $\to$→ FeCl₂$+$+ FeCl₃ $+$+_-------

Answer 1

Fe₃O₄(s) $+$8HCl(l)$\to$FeCl₂(s) $+$2FeCl₃(s) $+$4H₂O(l)

• In this reaction, iron oxide reacts with hydrochloric acid to produce ferrous chloride, ferric chloride, and water.
• A balanced chemical equation is an equation in which the total number of each atom present on the reactant side and product side are equal.
• The reactants are iron oxide and hydrochloric acid. The products are ferrous chloride, ferric chloride, and water.
• The number of atoms in both sides, Fe = 3, O =4, H = 8, Cl = 8.
• So the reaction is balanced.

The equation for the chemical reaction Fe₃O₄(s) $+$8HCl(l)$\to$FeCl₂(s) $+$2FeCl₃(s) $+$4H₂O(l) is a balanced equation.
