Answer:
The temperature of the gas after it is filled is 596 K
Explanation:
According to Gay-Lussac law, the pressure of a gas mass is directly proportional to temperature to a constant volume. That means than if pressure rise, the temperature too. We can assume then the volume is constant because the tank is isolated. The tank will be full when pressure will be in equilibrium, that means when pressure will be 1 atm because it is environment pressure. Using the following equation:
P1 /T1 = P2 /T2 and replacing, T2 = P2 *T1 / P1 = 1 atm * 298K / 0.5 atm = 596 K.

Polyatomic ion: a covalently bonded group of atoms that has a positive or negative charge and acts as a unit.
Acetic acid is a weak acid. So, the undissociated acid molecules exist in equilibrium with the dissociated form. The equilibrium representing the weak acidic nature of acetic acid is,
The interior of the cell membrane is hydrophobic. So, the membrane allows uncharged species (hydrophobic) to pass through it. Charged groups cannot easily pass through the membrane. We can say acetic acid can easily pass through the membrane when compared to the charged form acetate ion. At low pH, more of the molecule will cross the membrane as most of the acetic acid will be in undissociated and uncharged form at a lower pH.
of acetic acid is around 4.8. So at a pH value less than 4.8, we can say the more of the acetic acid molecules can cross the membrane.
