Question

Balance the chemical equation. ___Mg + ___Fe2O^3 -> ___MgO + ___Fe

Answer 1

Answer:

3Mg + Fe₂O₃ → 3MgO + 2Fe.

Explanation:

• To balance the equation, you should apply the law of conservation of mass for the equations.

• The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).

• The balanced equation is:

3Mg + Fe₂O₃ → 3MgO + 2Fe.

That 3.0 mole of Mg react with 1.0 mole of Fe₂O₃ to produce 3.0 moles of MgO and 2.0 moles of Fe.

• The no. of all atoms is the same in both of reactants and products side.

Mg (3), Fe (2), and O (3).
