Answer:
Will the electronegativity of barium be larger or smaller than that of strontium? Explain. EN of Ba (0.89) is smaller than EN of Sr (0.95). Because of larger size and more inner core e- shielding, Barium will more readily share its valence electron in the 6s sublevel than Sr will share it valence e- in the 5s sublevel.

Answer:b
Reason
A. They have more energy than a in a solid not less
B. Particles in a liquid are faster than a solid but slow than a gas. They are closer together than a gas but further apart then a solid.
C. Particles in a solid are as slow as they can get.
D. They are closer then in plasma
Answer:
121.8bar
Explanation:
The partial pressure is the pressure a gas would exert if it were alone in the volume of the gas mixture;
Given parameters:
Total pressure = 2558psi
Partial pressure of carbon dioxide = 54.6bar
Unknown:
Partial pressure of nitrogen dioxide gas = ?
Solution:
Total pressure = partial pressure of carbon dioxide + partial pressure of nitrogen dioxide gas
Let us convert from psi to bar;
14.504psi = 1 bar
2558psi = = 176.37bar
Now;
Partial pressure of nitrogen oxide = 176.37bar - 54.6bar = 121.8bar
