Under which conditions will gases best dissolve in liquids? А. when the pressure is low and the temperature is low
B. when the pressure is high and the temperature is high
C. when the pressure is low and the temperature is high
D. when the pressure is high and the temperature is low

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.  

d.) circle motion requires a force to give it a centripetal acceleration.

the answer is d.) potassium
