Answer:
The pKa of ethanol is higher than the pKa of water.
Explanation:
The Question above asked us to determine or Predict the relative pKa values of benzoic acid in water and in 95% ethanol.
So, there is going to be a higher pKa recorded for the ethanol than the pKa of water.
The reason is because the ka value will be larger for benzoic acid in water(that is the benzoic acid will act more as an acid here) and there will be less value for ka in 95% ethanol( that is the benzoic acid will act as less acid here than in water).

Answer:
The pressure of H₂(g) = 741 torr
Explanation:
Given that:
The atmospheric pressure measured in the lab = 765 torr
The vapor pressure of water = 24 torr
By applying Dalton's Law of Partial Pressure :
Making The Pressure inside the tube due to the H₂(g) the subject of the formula :
we have:
= (765 -24) torr
= 741 torr
The atmosphere is a envelope of gases surrounding another planet and the troposphere is the lowest part of the atmosphere
