In your own words, describe a pure substance. How can elements as well as compounds be considered pure substances.

Marizza181 [45]

Answer:

Pure compounds include elements and compounds where a combination of two or more pure substances is a mixture. Only one type of atom comes in the form of a pure element. Multiple atoms consist of a molecule and different atoms consist of a compound. These are all pure substances and individually.

The following combinations are not allowed. If n and ml are correct, change the l value to create an allowable combination:

The allowable combination for the atomic orbital is n=3, l=1, $m_{l}$ =-1.

<h3>What are the three quantum numbers of an atomic orbital?</h3>

Three quantum numbers specify an atomic orbital:

- The principal quantum number, n, which is a positive integer, describes the relative size of the orbital and its distance from the nucleus.

- l is the angular momentum quantum number that is related to the shape of the orbital; l is an integer from 0 to n-1 (so n limits l ),

- $\boldsymbol{m}_{l}$ is the magnetic quantum number that prescribes the three-dimensional shape of the orbital around the nucleus; $m_{l}$ values are integers from -l to =l(l limits ml)

For n = 3, l can have three values: 0, 1, and 2. Since $m_{l}$ values are integers from -l to 0 to +l, for l = 0 the value of $m_{l}$ cannot be -1 (l = 0 has $m_{l}$ = 0).

There are two l values that are consistent with n and $m_{l}$ values:

l=1 or 2

Therefore, the allowable condition is n=3, l=1, $m_{l}$ =-1.

You begin pouring sodium chloride into a glass of water. For a long time, the sodium chloride just dissolves in the water, but s

Gennadij [26K]

Answer:

Option D: The water is saturated

Explanation:

Solubility is the term used to designate the maximum amount of a solute that can be dissolved in a given amount of solvent, at a given temperature and pressure.

At start, you begin with pure water in the glass. This water is a pure substance, not a solution.

When you begin pouring sodium chloride into the glass of water, a solution, i.e. a homogenous mixture of solute and solvent, is formed.

This solution, at first, is diuted, which means that it contanins just few grams (matter) of the solute dissolved.

As, more sodium chloride is dissolved, the solution becomes more concentrated but is unsaturated. At some point, the water cannot dissolve more sodium chloride, because it has reached the maximum amount that can contain at that temperature and pressure. Then, the solution is saturated.

You can tell that the water is saturated, ie it contaiins the maximum amount of sodium chloride that can be dissolved, by that amount of water, at the given temperature, because from that point, you will note that as you pour more sodium chloride, it begins to pile up at the bottom of the glass. Hence, the true statement is the letter D: the water is saturated.
