  2. BA large molecule built from many repeating smaller units called monomers
  3. CA mixture of several different elements
  4. DAn ion with more than one charge
7.困难

Steel can be protected from rusting by coating it with zinc (galvanising). Why does the steel stay protected even if the zinc coating is scratched?

  1. AZinc absorbs all the water from the air
  2. BZinc is more reactive than iron, so it corrodes instead of the iron
  3. CZinc turns the iron into a noble metal
  4. DZinc is less reactive than iron, so it pushes oxygen and water away from the iron
8.困难

Burning a match is strongly exothermic, so why does it not catch fire until it is struck?

  1. AStriking makes the reaction endothermic
  2. BStriking pushes extra oxygen into the chemicals of the match head
  3. CStriking supplies the activation energy to start the reaction
  4. DThe match must first absorb all its energy from the air
