Carla and Maurice are recording the temperatures of classrooms at their school, but they’re using two different thermometers. They plan to present their readings in both kelvins and degrees Celsius. Help the students convert their temperatures from one scale to the other. Type the correct answer in each box.

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 is a! (2.9 x 10^-18 j) hope i could someone. : )
