Copper(II) sulfide is oxidized by molecular oxygen to produce gaseous sulfur trioxide and solid copper(II) oxide. Rule 3 is required because fluorine attracts electrons more strongly than any other element, for reasons you will discover in Chapter 6. As a result, the oxygen atoms acquire a negative charge and form oxide ions (O2). MgO when dissolves in water, itp forms magnesium hydroxide, which is basically in nature. 5 i. be able to use experimental data to calculate: empirical formulae. Students will also need the relative atomic masses. Remember that oxidation states are useful for visualizing the transfer of electrons in oxidationreduction reactions, but the oxidation state of an atom and its actual charge are the same only for simple ionic compounds. There are many types of redox reactions. This matches what happens in the reaction. Calculations of empirical formula may involve composition by mass or percentage composition by mass data.
