An electron is a subatomic particle. It is charged with negative electricity and is found in all atoms acting as the primary carrier of electricity in solids. They exist in spherical shells in various radii, which can in turn represent the energy levels. As the spherical shell is larger, there is higher energy contained in the electron. The electron mass at rest is approximately 9.11 x 10 to the exponent of -31 kilograms.

One of the pieces of evidence supporting energy quantization was the line spectra of elements. Why does this demonstrate energy
bezimeni [28]

Answer:

c) There are sharp emission lines demonstrating discrete energy levels.

Explanation:

When an element emits energy in the form of radiation, it produces a spectrum of colors on a photographic plate. This spectrum can either be continuous or discrete. In continuous spectrum the spectrum continues without any discrimination between two regions. This represents the continuous emission of radiation, and thus the continuous emission of energy without any break.

On the other hand, the line spectrum consists of discrete and sharp lines, which shows the emission of radiation in a certain amount in a certain time, with a break between emission. Hence, the line spectra supports the quantization of energy.

The correct option is:

<u>c) There are sharp emission lines demonstrating discrete energy levels.</u>

Carbon disulfide is prepared by heating sulfur and charcoal. The chemical equation is S 2 ( g ) + C ( s ) − ⇀ ↽ − CS 2 ( g ) K c
bezimeni [28]

Answer:

974.6 grams of CS2 can be prepared.

Explanation:

<u>Step 1:</u> Data given

Kc = 9.40 at 900 K

Moles of S2 = 14.2 mol

volume = 6.30 L

Molar mass of CS2 = 76.14 g/mol

<u>Step 2:</u> The balanced equation:

S2(g)+C(s) ↔ CS2(g)

<u>Step 3:</u> Calculate initial concentrations

Concentration of S2 = moles S2  / volume

Concentration of S2 = 14.2 moles / 6.30 L

Concentration of S2 = 2.25 M (This is the initial concentration)

The initial concentration of C and CS2 is 0M

Since the mole ratio is 1:1:1

There will react X

The concentration of S2 at the equilibrium is: (2.25 -X)M

The concentration of C and CS2 at the equilibrium is X M

<u>Step 4:</u> Calculate concentrations

Since C is not a gas but solid, it doesn't matter for the Kc

Kc = 9.40 = (products)/(reactants) = [CS2(g)]/[S2(g)]

9.40 = X/(2.25-X)

X = 2.034 = [CS2]

[S2] = 2.25 - 2.034 = 0.216

<u>Step 5</u>: Calculate moles of CS2

Moles CS2 = molarity CS2 * volume

Moles CS2 = 2.034 M * 6.30 L

Moles CS2 = 12.8 moles

<u>Step 6:</u> Calculate mass of CS2

Mass CS2 = moles CS2 * molar mass CS2

Mass CS2 = 12.8 moles * 76.14 g/mol

Mass CS2 = 974.6 grams

974.6 grams of CS2 can be prepared.
