5.Medium

Which equation shows a combustion reaction?

  1. AC₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
  2. BZn + CuSO₄ → ZnSO₄ + Cu
  3. CCaCO₃ → CaO + CO₂

A red blood cell is placed in pure water (a hypotonic solution). What happens?

  1. AWater leaves the cell, which shrinks and wrinkles
  2. BNothing happens to the cell
  3. CSalt enters the cell, which shrinks
  4. DWater enters the cell, which swells and may burst
7.Hard

Starch and cellulose are both made entirely of glucose units, yet humans can digest starch but not cellulose. Why?

  1. AStarch contains nitrogen, which makes it easier to digest
  2. BThe glucose units are linked differently, and humans lack an enzyme to break cellulose's links
  3. CCellulose is really made of amino acids, not glucose, so stomach acid cannot break it
  4. DCellulose dissolves in water, so it is lost from the gut
8.Hard

  1. AGroup 14 (carbon group)
  2. BGroup 1 (alkali metals)
  3. CGroup 18 (noble gases)
  4. DGroup 17 (halogens)
