Answer:
Explanation:
Graham’s Law applies to the diffusion of gases:
The rate of diffusion (r) of a gas is inversely proportional to the square root of its molar mass (M).
If you have two gases, the ratio of their rates of diffusion is
The time for diffusion is inversely proportional to the rate.
Data:
t₂ = 222 s
t₁ = 175 s
M₁ = 28.01
Calculation
:
It is always the same as it was before the collision because there is no outside forces it is left with the same amount of energy throughout thee collision.
Answer:
A substance containing only one type of atom or one type of molecule is a pure substance. Most of the matter around us, however, consists of mixtures of pure substances. Air, wood, rocks and dirt are examples of such mixtures. Mixtures can be further classified as Homogeneous and Heterogeneous.
