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

Answers

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).
