WHOEVER ANSWERS THIS CORRECTLY WILL GET 20 POINTS

Condensation occurs at 0 degree C is false.

Explanation:

Condensation is simply the change of matter from a gas to a liquid.  If the surrounding pressure of the vapor is higher than the vapor pressure at a particular temperature, then condensation will occur.  This means that temperature is more of an estimate and not an absolute when it comes to condensation, and likewise evaporation.

Looking at this graph, we see a near-linear correlation of temperatures; however, condensation is about pressure changes rather than temperature.  So, you could say the process is temperature independent.

Perhaps this is what you are looking for...?  Anyway, cheers.

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.
