Explain how the process of distillation can be used to remove dissolved impurities from a sample of water.

The steam then cools and condenses to from purified water. Distillation effectively removes inorganic compounds such as metal (lead), nitrate, and other nuisance particles such as iron and hardness from a contaminated water supply. The boiling process also kills microorganisms such as bacteria and some viruses.

Explanation:

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the answer to this question is 3.
