A helium balloon has a volume of 17.3 L
when the pressure is 1.375 atm and the tem-
perature is 19°C. The balloon is cooled at
a constant pressure until the temperature is
-15°C. What is the volume of the balloon at
this stage?
Answer in units of L.

a chemical reaction

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.
