Question 9

Question
When can sodium chloride conduct electricity?
Answer

Question 10

Question
Sodium chloride and magnesium oxide have:
Answer
  • High melting points
  • Low boiling points
  • Strong electrostatic attractions between ions

Question 11

Question
The melting point of MgO is higher than NaCl because magnesium ions are smaller so they can get closer to oxygen ions, making the bond stronger therefore more energy is needed to break the bonds.

Question
What substances have low melting points due to their simple molecular structure?
Answer
  • Sodium chloride
  • Carbon dioxide
  • Water
  • Graphite

Question 15

Question
Why does carbon dioxide not conduct electricity?
Answer
  • There are no free electrons
  • It's not a metal and only metals conduct electricity
  • It's not a solid and only solids conduct electricity

Question 16

Question
Who arranged the elements in order in a table and left gaps where he thought new elements would be found?
Answer
  • Mendeleev
