  • What does the acronym 'LEO the lion goes GER' help you remember in redox reactions?
    'LEO' stands for 'Lose Electrons Oxidation' and 'GER' stands for 'Gain Electrons Reduction.'
  • What happens to the charge of a species when it loses electrons in a redox reaction?
    It becomes more positive because it is losing negatively charged electrons.
  • What is the oxidation number of an atom in its elemental form?
    The oxidation number is 0 for an atom in its elemental form.
  • How is the oxidation number of an ion determined?
    The oxidation number of an ion is equal to its charge.
  • What is the oxidation number of hydrogen when bonded to a nonmetal?
    Hydrogen has an oxidation number of +1 when bonded to a nonmetal.
  • What is the oxidation number of hydrogen when bonded to a metal?
    Hydrogen has an oxidation number of -1 when bonded to a metal.
  • What is the oxidation number of fluorine in compounds?
    Fluorine always has an oxidation number of -1 in compounds.
  • What is the oxidation number of oxygen in peroxides?
    Oxygen has an oxidation number of -1 in peroxides.
  • What is the oxidation number of oxygen in superoxides?
    Oxygen has an oxidation number of -1/2 in superoxides.
  • What is the typical oxidation number of oxygen in most compounds (excluding peroxides and superoxides)?
    Oxygen usually has an oxidation number of -2 in most compounds.
  • What is the oxidation number of Group 1A elements in compounds?
    Group 1A elements have an oxidation number of +1 in compounds.
  • What is the oxidation number of Group 2A elements in compounds?
    Group 2A elements have an oxidation number of +2 in compounds.
  • What role does a species play if it is oxidized in a redox reaction?
    If a species is oxidized, it acts as the reducing agent (reductant).
  • What role does a species play if it is reduced in a redox reaction?
    If a species is reduced, it acts as the oxidizing agent (oxidant).
  • What is Faraday's constant and what does it represent?
    Faraday's constant is 9.647 × 10^4 coulombs per mole of electrons and represents the charge of one mole of electrons.
