How is Hess's law used to calculate the enthalpy change of a reaction? A. The enthalpy of the products is subtracted from the enthalpy of
the reactants,
O B. The enthalpy is calculated from the experimentally determined
equilibrium constant.
C. The enthalpy changes of each step of the reaction are added
together
O D. The enthalpy is determined experimentally using a bomb
calorimeter.

oh it is true if thats what you are asking

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.
