(a)
Interpretation: The oxidation numbers of the given reactants and products are to be calculated. The given equation is to be balanced in acidic solution. The total number of electrons which are transferred for each uranium atom is to be calculated.
Concept introduction: The reactants and the products in a. given ionic equation must be balanced for the given number of ions or atoms of each element. A compound is said to be oxidized when it loses electrons which increases its oxidation number. On the other hand reduction is the process of gaining electrons which decreases the oxidation number of the compound. Usually the common oxidation numbers of elements are used to determine whether the given compounds are oxidized or reduced.
To determine: The oxidation numbers of the given reactants and products.
(b)
To determine: The balanced ionic equation from the given unbalanced ionic equation.
(c)
To determine: The total number of electrons which are transferred for each uranium atom.
