If the AH yap of acetone is 31.3 kJ/ mol and the ASvap of acetone is 95 J/mol K, what
is the AGvap at room temperature (25°C, 298K)? Does this substance boil?

a) AG vap is negative, which means that it doesn't
boil at this temperature.

b) AG vap is negative, which means that it does boil
at this temperature.

c) AGvap is positive, which means that it doesn't
boil at this temperature.

d) AG vap is positive, which means that it does boil
at this temperature.

samuel de champlain. in 1608, king henry iv sponsored pierre dugua, sieur de mons and samuel de champlain as founders of the city of quebec with 28 men. this was the second permanent french settlement in the colony of canada.

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.  

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
