Answer

Brief Explanations:

  • Question #12: Sugar is soluble in water while sand is not. This property allows their separation. Malleability and ductility are related to metals' ability to be shaped, and acidity is not relevant here for separation.
  • Question #13: Density is defined as mass per unit volume, so the formula is $D = m/V$, where $m$ is mass and $V$ is volume.
  • Question #14: The state of matter (solid, liquid, gas etc.) is a physical property as it can be observed without changing the substance's chemical identity.

Answer:

  • Question #12: C. soluble in water
  • Question #13: A. $D = m/V$
  • Question #14: True
