side. For balancing the number of magnesium atoms, we need to put 2 before Mg and the equation becomes, 2Mg + O 2 2MgO Now the number of magnesium and oxygen atoms is equal on both sides of the arrow and the chemical equation is said to be balanced. This method of balancing of a chemical equation is called the Hit and Trial method .
