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. What can be used to detect the presence of individual elements?

  • Clarifying with the periodic table
  • Emission Spectroscopy
  • Flame tests
  • Asking a scientist (although a good idea - please don't choose this)

Other questions in this quiz

2. What group are alkali metals in?

  • 1
  • 3
  • 7
  • 4

3. How do you test for a carbonate?

  • Add a dilute acid. If the gas produced bubbles off, test with limewater. If the limewater turns cloudy it contains CO2, meaning the carbonate is confirmed.
  • Blow it up, if the smoke is green carbonate is present.
  • Bubble it in HCl - it will fizz if carbonate is present.
  • Placing it in solution with silver nitrate, a white precipitate will be formed if carbonate is present.

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. Define 'simple molecular covalent compounds'

  • Small molecules consisting of only metallic atoms
  • Large molecules consisting of only metallic atoms
  • Small molecules consisting of only non-metallic atoms
  • Large molecules consisting of only non-metallic atoms
