Balance a chemical equation when given the unbalanced equation Explain the role of the Law of Conservation of Mass in a chemical reaction Even though chemical compounds are broken up and new compounds are formed during a chemical reaction atoms in the reactants do not disappear nor do new atoms appear to form the products Chemical Equations and the Law of Conservation of Matter In the previous section the reaction between hydrogen gas and oxygen gas to produce water in the gaseous phase was shown as a chemical equation H 2 g O 2 g H 2 O g At the molecular level the reaction would look something like this Notice that there are two oxygen atoms on the left hand side of the equation and only

To balance a redox equation using the half reaction method the equation is first divided into two half reactions one representing oxidation and one representing reduction The equations for the half reactions are then balanced for mass and charge and if necessary adjusted so that the number of electrons transferred in each equation is the same The balanced equation must now be used to convert moles of Fe s to moles of H 2 g Remember that the balanced equation s coefficients state the stoichiometric factor or mole ratio of reactants and products 3 74 x 10 5 mol Fe s 1mol H 2 g 1mol Fe s 3 74 x 10 5 mol H 2 g Step 5 Check units
N2 H2 NH3 On the left there is 2 N and 2 H On the right there is 1 N and 3 H If we tried to balance starting with H you d need to use a fraction or decimal and would get messy so let s start with N There s 2 on the left and 1 on the right so we need to change the coefficient of NH3 to 2 Now we have An equation is balanced by changing coefficients in a somewhat trial and error fashion It is important to note that only the coefficients can be changed NEVER a subscript the coefficient times the subscript gives the total number of atoms Four examples before balancing the equation d 3Ca NO Now back to balancing the example equation
