GCSE C2 CHEMISTRY ADDITIONAL EDEXCEL QUIZ

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. Why are metals able to conduct electricity?

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

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

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

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

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

4. Define 'giant molecular covalent compounds'

  • Large structure with many non-metallic atoms held together with covalent bonds
  • Small structure with many non-metallic atoms held together with ionic bonds
  • Large structure with many non-metallic atoms held together with ionic bonds
  • Large structure with many non-metallic atoms held together with metallic bonds

5. How do scientists use chromatography to identify colourless substances like amino acids and sugars>

  • Setting it on fire with a bunsen burner
  • Spraying the paper with a locating reagent which reacts with the invisible spots to produce a colour
  • Spraying the paper with universal indicator so the colourless substances change colour
  • Filtering it and seeing which colours are left
