The boiling point depends on the strength of the intermolecular forces holding the molecules together. Greater the force, higher is the boiling point.
The intermolecular force increases in the order shown below:
ion-ion > H-bonding > dipole-dipole > London dispersion
CH3CN is a polar molecule with strong dipole-dipole forces
CH3CH2CH3 is non-polar held by london dispersion
Ar exist as a gas. It will have a lowest boiling point
Thus the order of decreasing b.pt is:
CH3CN > CH3CH2CH3 > Ar
I had an examon this on Friday, I'm pretty positive theanswer is C. The reason is when there is combusion, there is an exothermic change, or energy is being released
Answer: Aluminum, Antimony, Arsenic, Bismuth, Carbon, Cadmium, Chromium, Cobalt, etc.
What does the Bible teach us on how to pray to God?
- <em>Jesus</em><em> </em><em>taught</em><em> </em><em>that</em><em> </em><em>when</em><em> </em><em>we</em><em> </em><em>pray</em><em> </em><em>we</em><em> </em><em>should</em><em> </em><em>not</em><em> </em><em>be</em><em> </em><em>like</em><em> </em><em>hypocrites</em><em> </em><em>and</em><em> </em><em>when</em><em> </em><em>you</em><em> </em><em>pray</em><em> </em><em>go</em><em> </em><em>to</em><em> </em><em>your</em><em> </em><em>room</em><em>,</em><em> </em><em>close</em><em> </em><em>the</em><em> </em><em>door</em><em> </em><em>and</em><em> </em><em>pray</em><em> </em><em>to</em><em> </em><em>your</em><em> </em><em>father</em><em> </em><em>who</em><em> </em><em>is</em><em> </em><em>unseen</em><em>.</em>
