Answer:
P(H₂) = 807.2 torr
Explanation:
According to the Dalton law, the pressure of mixture of a gas is sum of the partial pressure of its mixing component gases.
P(total) = P1 + P2 + P3 +....
In given problem,
Total pressure is = 794 torr
Partial pressure of water = 13.2 torr
Partial pressure of hydrogen = ?
Solution:
P(total) = P(H₂O) + P(H₂)
P(H₂) = P(total) - P(H₂O)
P(H₂) = 794 torr - 13.2 torr
P(H₂) = 807.2 torr

Answer:
Chlorine has higher ionization energy.
Explanation:
Sodium is present on left side of periodic table in period 3 while chlorine is present on right side of periodic table in period 3.
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required. Thus chlorine have higher ionization energy as compared to the sodium.
