For N₂ + 3H₂ → 2NH₃, 1 mol of N₂ is mixed with 2 mol of H₂. Which reactant is limiting?

  1. ANeither, because both are used up exactly
  2. BH₂, because 1 mol of N₂ would need 3 mol of H₂
  3. CN₂, because there is less of it

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
