WebBalancing Equations using Reacting Masses If the masses of reactants and products of a reaction are known then we can use them to write a balanced equation for that reaction This is done by converting the masses to moles and simplifying to find the molar ratios Worked Example Example 3 A student reacts 1.2 g of carbon with 16.2 g of zinc oxide. WebThe change in massof a reactant or product can be followed during a reaction. This method is useful when carbon dioxide is a product which leaves the reaction container. It is not …
