In this experiment, students observe the redox reaction between copper(II) oxide and magnesium, demonstrating magnesium's ability to remove oxygen from an oxide of copper, and hence the relative positions of copper and magnesium in the reactivity series For example, it has been proposed that one factor that contributed to the fall of the Roman Empire was the widespread use of lead in cooking utensils and pipes that carried water. We can balance oxidationreduction reactions in solution using the oxidation state method (Table \(\PageIndex{1}\)), in which the overall reaction is separated into an oxidation equation and a reduction equation. Iron and oxygen (O_2) gas react to form iron(III) oxide. However, we can still assign oxidation states to the elements involved by treating them as if they were ionic (that is, as if all the bonding electrons were transferred to the more attractive element). To determine the oxidation states of the individual carbon atoms, we use the same rules as before but with the additional assumption that bonds between atoms of the same element do not affect the oxidation states of those atoms. Thus the sum of the oxidation states of the two carbon atoms is indeed zero. Write a balanced equation and indicate the states for the reaction: burning hydrogen (g) in oxygen (g).
