Based on the kinetic molecular theory, which of the following statements is correct about the particles in a sample of gas at a constant temperature and volume? They attract each other with strong forces.
Their net kinetic energy decreases due to collisions.
They have negligible kinetic energy.
There is a lot of empty space between them.

my sources say that there is a lot of empty space between then

Explanation:

their forces to attract each other is not strong

kinetic energy is always high in gasses

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 old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
