Mg + Fe2O3→ Fe +mgO
The coefficients needed to balance the reaction above is 3, 1,2,3
the reaction is a single replacement reaction/ single displacement reaction
The balanced equation is is therefore
= 3Mg + Fe2O3 → 2Fe + 3MgO
- The equation above is balanced since it obey the law of mass conservation. that is the number of atom in side of reactant is equal to number of atoms in product side.
- for example there is 3 atoms of Mg in reactant side and 3 atoms of Mg in product side.
The reaction is a single replacement reaction because Mg replaces Fe from its compound.
