What distinguishes effusion from diffision? How are these processes similar?

Chemistry
1 answer:
zvonat [6]4 years ago
7 0

Answer:

In effusion, a substance escapes through a tiny pinhole, or other hole whereas diffusion is the spreading out of a substance within a dispersing medium.

Effusion and diffusion are similar in terms of rates and speeds.

Explanation:

According to effusion, if there is a small hole in a container, a gas will leak from it. So, in this process a substance escapes through a tiny pinhole, or other hole.

According to diffusion, the two solutions will reach the lowest possible concentration of both, if they are combined and not mixed. So, diffusion is the spreading out of a substance within a dispersing medium.

Effusion and diffusion are similar in terms of rates and speeds.

Why does the solution decolorize on standing after the equivalence point has been reached?
Arisa [49]

The equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant.

Depending on the concentration of titrant we could be adding little excess of it and this may result in persistence of color of solution. After continuous stirring for a while the excess titrant may react with dissolved CO₂ in air and thus decolorizing the solution.

What are the two main components of the internal energy of a substance? On what are they based?
Lana71 [14]

The 2 main components of the internal energy of a substance are:

The internal energy is a sum of kinetic and potential energy.

E_k (total)=E_k(translational) + E_k(rotational) + E _k(vibrational)

Internal energy is the microscopic energy contained in a substance, given by the random, disordered kinetic energy of the molecules. Further it includes the potential energy between those molecules, and the nuclear power contained in the atoms of those molecules.

The internal energy of a system is extensive property. it's  a state property. The exchange is independent of the path followed. Change in internal energy of a cyclic process is 0.

Internal energy is affected by factors including pressure, volume, and temperature. All the variables on this listing are state functions.

Electron X can change to a higher energy level or a lower energy level. Which statement is true of electron X?
rosijanka [135]

Answer: 2) Electron X absorbs energy when it changes to a higher energy level.

Explanation:

The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).
