In order for the molecule to change phase from liquid to gas and evaporates, it needs to overcome the force from other molecules around it. as the force bigger evaporation gets harder. so e has the highest force and higher boiling point.
Answer:
3.4L
Explanation:
Given parameters:
Initial Volume of gas = 6.8L
Initial temperature of gas = 325°C = 325 + 273 = 598K
Final temperature = 25°C = 25 + 273 = 298K
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply the Charles's law. It can be expressed as;
=
V and T are volume and temperature
1 and 2 are initial and final states
Now insert the parameters and solve;
=
2026.4 = 598V2
V2 = 3.4L
Answer:
Half - filled electronic configuration.
Explanation:
Nitrogen is unreactive because it has half filled configuration which is stable and unreactive.

Answer:
47.42 amu.
Explanation:
The following data were obtained from the question:
Isotope A (Bl–47)
Mass number = 46.91 amu
Abundance = 53.4%
Isotope B (Bl–48):
Mass number = 47.98 amu
Abundance = 46%
Isotope C (Bl–50)
Mass number = 50.12 amu
Abundance = 100 – (53.4 + 46)
Abundance = 100 – 99.4
Abundance = 0.6%
Average atomic mass of Blairium =?
The average atomic mass can be obtained as follow:
Average atomic mass = [(mass of A × A%)/100] + [(mass of B × B%)/100] + [(mass of C × C%)/100]
Average atomic mass = [(46.91 × 53.4)/100] + [(47.98 × 46)/100] + [(50.12 × 0.6)/100]
Average atomic mass = 25.05 + 22.07 + 0.3
Average atomic mass = 47.42
Therefore, the average atomic mass of blairium is 47.42 amu.
