Q: How does the distillation apparatus remove impurities from water?

Q: Why does water vapour condense in the condenser tube?

Q: As the boiling animation neared the end, what does the change in the proportion of particle types in the boiling flask indicate about the impurities?

Q1) Distillation relies on evaporation to purify water

Explanation:

contaminated water is heated to form steam. inorganic compounds and large non-volatile organic molecules do not evaporate with the water and are left behind. The steam then cools and condenses to form purified water

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
