He, because it’s a noble gas which they have full valence electrons (occupied energy levels)
Answer:
VP as function of time => VP(Ar) > VP(Ne) > VP(He).
Explanation:
Effusion rate of the lighter particles will be higher than the heavier particles. That is, the lighter particles will leave the container faster than the heavier particles. Over time, the vapor pressure of the greater number of heavier particles will be higher than the vapor pressure of the lighter particles.
=> VP as function of time => VP(Ar) > VP(Ne) > VP(He).
Review Graham's Law => Effusion Rate ∝ 1/√formula mass.
Answer:
False
Explanation:
The relationship between energy and amplitude can be written as eαa^2
This means that the energy of a wave is directly proportional to the square of the amplitude.
Not all matter in the reactant goes to the product. Some matter is byproducts.
