3.Makkelijk

According to the kinetic molecular theory, how do gas particles move?

  1. AOnly when heated, and then in neat lines between the walls
  2. BConstantly, randomly and in straight lines between collisions
  3. CSlowly in fixed positions
  4. DAlways in a single direction, set by the pull of gravity
4.Gemiddeld

Wat is de dichtheid van een voorwerp met een massa van 50 g en een volume van 20 cm³?

  1. A2,5 g/cm³
  2. B70 g/cm³
  3. C1000 g/cm³
  4. D0,4 g/cm³
5.Gemiddeld

Which bond joins amino acids together in a protein?

  1. AA peptide bond
  2. BAn ionic bond
  3. CA glycosidic bond
  4. DA hydrogen bond
6.Gemiddeld

When mercury(II) oxide is heated, it reacts as 2HgO → 2Hg + O₂. What type of reaction is this?

  1. ASynthesis
  2. BSingle replacement
  3. CCombustion
  4. DDecomposition
7.Moeilijk

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

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

Which approach best reduces a health worker's exposure to ionising radiation?

  1. ALimit the time near the source, increase the distance and use shielding
  2. BRely only on wearing gloves
  3. CStand closer to the source so the job is finished sooner and exposure is shorter
  4. DWork faster without any shielding
