The given MgO(s) + Fe(s) → Fe 2 O 3 (s) + Mg(s) reaction has to be balanced. Concept introduction: Balancing reaction: Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side. Steps in balancing the information Step 1: Write the unbalanced equation Step 2: Find the coefficient to balance the equation. The coefficient should be reduced to the smallest whole number.
