Chemical reactions project modeling the conservation of mass pls help just need answer

The law of conservation of mass states that

In any chemical reaction mass is neither created nor destroyed rather it remains conserved

Look the chemical reaction below

Count the mass on both sides and simplify

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.
