Sulfuric acid (Hsub2SOsub4), hydrogen sulfide (Hsub2S), carbonic acid (Hsub2COsub3), chromic acid (Hsub2CrOsub4), and oxalic acid (Hsub2Csub2Osub4) are all examples of diprotic acids
Explanation:
(a) The given data is as follows.
Temperature (T) = = (25 + 273) K = 298 K
= 43000 J/mol
Since, both the liquid and vapors are at equilibrium. Therefore, change in free energy will be calculated as follows.
= 0
43000 - = 0
= -144 J/mol K
Negative sign indicates an increase in entropy of the system.
Now, for 1 mole of is as follows.
= 144 J/K
So, - 214 = 144 J/k
= 358 J/K
Therefore, we can conclude that entropy of vapor is 358 J/K.
(b) As we know that intensive variable are the variables which do not depend on the amount of a substance.
So, in the given situation only temperature will act as an intensive variable that will be required to completely specify the vapor-liquid mixture of .

Answer:
Antimony, it increases as it goes across a period and decreases as it goes down a group. Does potassium or lithium have the smaller atomic radius? Lithium, because as you move across a period it gets weaker and down a group, it gets stronger.
