How do landmasses impact the movement of air and water? (A) They stop all movement of both air and water.

(B) They speed up the air and water and allow it to pass though.

(C) They change the direction and slow them down.

(D) They slow down the air but speed up the water.

Explanation:

(B) They speed up the air and water and allow it to pass though.

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.
