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).
