A sample of 10.5 g of nitrogen reacts with 20.2 g of hydrogen to produce ammonia. (36 points

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

Lera25 [3.4K]

The allowable combination for the atomic orbital is n=4, l=2, $m_{l}$ =2.

<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 = 4, l can four values: 0, 1, 2, and 3. To be consistent with $m_{l}$ =+2the l value must be higher than 1. There are two l values that are consistent with n and $m_{l}$ values: l= 2 or 3

Therefore, the allowable condition is n=4, l=2, $m_{l}$ =2

Calculate the molecular mass of the nonionic solutes.

3241004551 [841]

Answer:

The molecular mass of the nonionic solutes is 124,90 g/m

Explanation:

This is the formula for boiling point elevation.

ΔT = Kb . m

Where ΔT = Tb (solution) - Tb (pure solvent)

Where Kb = the ebullioscopic constant

Where m = molality (moles of solute in 1kg of solvent)

Kb for water is 0,512°C/molal

100,680°C - 100°C = 0,512°C/molal . m

0,680°C = 0,512°C/molal . m

0,680°C /0,512 molal/°C = m

1,32 molality (This are my solute moles in 1kg (1000g) of solvent but I have just 390 g, so let's build the rule of three)

1000 g _____ 1,32 moles

390 g ______ (3,90 g . 1,32 moles) / 1000 g = 0,5148 moles

Molecular mass = g/ mol (mass/moles)

64,3 g /0,5148 moles = 124,90 g/m

The heat of solution is found by adding a salt to water in a calorimeter and measuring the temperature change. The specific heat

melomori [17]

Answer:

The heat of the solution of salt is 1.66.11 J/g.

Explanation:

Mass of the water = m = 46.52 g

Initial temperature of the water = $T_1=22.83 ^oC$

Final temperature of the water = $T_2=18.98^oC$

The specific heat of water, c = 4.180 J/gºC

Heat associated with water on dissolving salt: q

$Q=mc(T_2-T_1)$

$Q=46.52 g\times 4.180 J/g&oC\times (18.98^oC-22.83 ^oC)$

$Q=-748.65 J$

Negative sign means that heat was lost by water on an addition of a salt.

Heat released on dissolving of salt = -Q = 748.65 J

Mass of salt added = 4.5069 g

Heat of the solution of salt :

= $\frac{-Q}{ 4.5069 g}=\frac{748.65 J}{ 4.5069 g}=1.66.11 J/g$

The heat of the solution of salt is 1.66.11 J/g.

The Mohs scale measures A. density of a mineral. B. a mineral’s hardness. C. the luster of a mineral. D. a mineral’s type of cry

disa [49]

B- The Moh's Hardness Scale is 0-10 starting with talc and ending with diamonds that ranks the hardness of minerals. A minerals hardness can be determined by if it scratches another mineral, it is harder, and if it is scratched, it is softer.
