This resource doesn't cover one specific topic or the whole of C2. I have made flash cards (not electronically) and when filtering through them I have made this quiz to help me remember all the flash cards I didn't know. Please don't take this as a staple revision source - this only has a few random pieces from different topic areas.

1. Which forces are strong in covalent bonds and which are weak?

  • Strong forces between the atoms, weak forces between the elements
  • Strong forces between the atoms of the molecules, weak forces between the molecules
  • Strong forces between the elements, weak forces between the atoms
  • Strong forces between the molecules, weak forces between the atoms

2. How do you test for chloride ions?

  • Add silver nitrate, if a precipitate forms it contains chloride ions.
  • Bubble it through limewater - if a blue precipitate is formed it contains chloride ions.
  • Dip a nichrome wire in acid and dip it in the substance, put it in a bunsen burner and the flame will turn blue if chloride ions are present.
  • Add water sterilising tablets. If it turns cloudy, chloride ions were present, as chlorine is present in a swimming pool.

3. Why are metals able to conduct electricity?

  • Because they're soluble in water
  • Because the delocalised electrons can move when a voltage is applied
  • Because the neutrons are delocalised and can move when a voltage is applied
  • Because the protons are able to move

4. What is the equation for chromatography?

  • 3.14 x r^2
  • distance traveled by component x distance traveled by solvent
  • distance traveled by component / distance traveled by solvent
  • e = mc^2

5. Why does graphite conduct electricity?

  • Because graphite is derived from carbon
  • Because it does (plz also don't choose this)
  • The electrons in the weak bonds between the layers of graphite can move when a voltage is put across them.
  • The protons are the same size
