Answer:

The unknown temperature is 304.7K

Explanation:

V1 = 100mL = 100*10^-3L

P1 = 99.10kPa = 99.10*10³Pa

V2 = 74.2mL = 74.2*10^-3L

P2 = 133.7kPa = 133.7*10³Pa

T2 = 305K

T1 = ?

From combined gas equation,

(P1 * V1) / T1 = (P2 * V2) / T2

Solving for T1,

T1 = (P1 * V1 * T2) / (P2 * V2)

T1 = (99.10*10³ * 100*10^-3 * 305) / (133.7*10³ * 74.2*10^-3)

T1 = 3022550 / 9920.54

T1 = 304.67K

T1 = 304.7K

Distinguish between a solution in general and an aqueous solution
Sveta_85 [38]

Answer:

  • What distinguish a solution in general from an aqueous solution is the solvent. A solution in general may contain any solvent, which may be solid, liquid or gas, while an aqueous solution is formed with water as solvent.

Explanation:

A solution in general is a homogeneous mixture in which a substance, named solute, is dissolved, in other substance, name solvent.

Solutions may be in solid, liquid or gas state. There are many kind of solvents. Usually, in a lab you work with liquid solutions. Some liquid solvents are: ethanol, glycerin, hexane, benzene, and water, among many others.

Aqueous solution is a solution where the solvent is water. Of course, the solute may be any one: NaCl, sugar, ethanol, an acid, a base, a salt.

What distinguish a solution in general and an aqueous solution is the solvent.

An electron in a hydrogen atom has orbital quantum number l = 7. how many possible values of the magnetic quantum number ml coul
MA_775_DIABLO [31]

A total of 15 magnetic quantum values are possible.

<h3>What is a Magnetic quantum number?</h3>

One of the four quantum numbers that describe an electron's position in relation to the nucleus is its magnetic quantum number.

Between spin and azimuthal quantum numbers, the magnetic quantum number comes in third on the list. The electron is positioned in one of the various orbitals formed by the division of the subshells (such as s, p, d, and f). It specifies the spatial direction of an orbital of certain energy (n) and form (I). The number of orbitals in each subshell is given as 2+1, where is the azimuthal quantum number. We can determine the orbital in each sub-shell using that method.

We are aware that there are between -l and +l conceivable magnetic quantum numbers.

Here l = 7

Thus, the range of magnetic quantum numbers will be -7 to +7.

Thus, the magnetic quantum numbers are as follows:

-7, -6, -5, -4,-3,-2,-1, 0, 1,2,3,4, 5, 6,7

This opens up a total of 15 magnetic quantum numbers.
