bazaltina [42]3 years ago
3 0

Answer:

solvent (such as water, oil or isopropyl alcohol) is allowed to absorb up the paper strip. ... Different molecules run up the paper at different rates. As a result, components of the solution separate and, in this case, become visible as strips of color on the chromatography paper.

Explanation:

Hope this helps leave a heart c:

A plot of the maxwell distribution of speeds for the same sample of gas at different temperatures shows that.
Eva8 [605]

The same sample of gas at different temperatures shows that at low

temperatures, most molecules have speeds close to their average

speed.

<h3>What does the Maxwell-Boltzmann distribution graph show?</h3>

Put simply, a Maxwell-Boltzmann distribution graph shows how the energy of gas particles varies within a system.

This is solely a measurement of the speeds of particles because kinetic energy is directly related to speed.

The Maxwell-Boltzmann distribution in chemistry is the subject of this article.

We will begin by describing how to read a graph of the Maxwell-Boltzmann distribution. This will involve taking a closer look at things like the typical energy and the most likely energy.

The graph will then be changed under various circumstances, such as when a catalyst is added or the temperature is raised.

The Maxwell-Boltzmann distribution, which we previously mentioned, is a probability function that depicts the distribution of energy among the particles of an ideal gas. (For more information on this topic, see Chemical Kinetics.)

In an experiment magnesium ribbon was heated in air. The product was found to be heavier than the original ribbon. Potassium man
KatRina [158]

Burning a magnesium ribbon in the air is an addition reaction while heating potassium manganate 7 is a decomposition reaction.

<h3>Addition and decomposition reactions</h3>

Magnesium burns in air to produce magnesium oxide as follows:

2Mg + O_2 --- > 2MgO

Potassium manganate 7 burns to produce multiple products as follows:

2 KMnO_4 --- > K_2MnO_4 + MnO_2(s) + O_2

Thus, the MgO will be heavier than Mg. On the other hand, MnO_2 will be less heavy than KMnO_4.

Which of the following has to remain constant to allow you to use the combined gas law for calculations?
Mazyrski [523]

Answer:

Amount of gas

Explanation:

The combined gas law has to do with pressure, volume, and temperature. All of them can be a variable that you have to solve for. However, amount of gas is not a variable you can solve for, which means it must remain constant.

What are the first two quantum numbers for the electrons located in subshell 4d?
SCORPION-xisa [38]

Answer:

n = 4, l = 2

Explanation:

The number 4 in 4d is the principal quantum number (n).

The letter d in 4d tells us that we have a d orbital, as determined by the <em>secondary quantum number (l</em>).

The quantum number l tells us the shape of the orbital.

l = 0     s orbital

l = 1      p orbital

l = 2     d orbital
