2. Why is NaCl not called "Sodium(I) Chloride" ?

  • Because sodium's O.N is always +1. Roman numerals are only used for variable oxidation state elements
  • Because it should be Sodium Chloride (I)
  • Because Chlorine is always -1, therefore sodium must be in a 1:1 ration hence NaCl
  • Because the compound is so well known it becomes redundant

3. What would Iron (III) Chloride be?

  • Fe2Cl6
  • Fe3Cl
  • FeCl3
  • Fe6Cl3

4. Which of these isn't describing oxidation?

  • The change that occurs to a reducing agent
  • Addition of Hydrogen
  • Loss of electrons
  • Addition of Oxygen

5. Name this compound using oxidation number nomenclature: K2MnO4

  • Potassium (II) Manganate (VII)
  • Potassium Manganate (VI)
  • Potassium Manganate tetra oxide
  • Potassium (I) Manganate
