Which best describes what a refrigeration system would do? O It adds cold air through the room.
O It moves the thermal energy to another place.
O Itallows coolant to release cold air into the room.
O It transfers energy from the ground.

It moves the thermal energy to another place.

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.  

answer carbon and three oxygen atoms;
