Answer:

the scattering and reflection of light by dust particles

Explanation:

The process of scattering is responsible for the different colors we see in the sky.

Different colors have have some different wavelengths, and hence, scatter accordingly.

The small dust particles that is present in the air , gets scattered as the light falls on the dust particles , and hence give various colors to the sky , since , blue is the color that is scattered the most , therefore , maximum sky is blue in color .

Similarly during night time , there is no light , hence , the sky appears dark.

A sample of nitrosyl bromide (nobr) decomposes according to the equation 2nobr(g)⇌2no(g)+br2(g) an equilibrium mixture in a 5.00

Alex73 [517]

Answer:

Kc = 0.122.

Explanation:

We can calculate Kc from the relation: Kc = [NO]².[Br₂] / [NOBr]².

Firstly, we convert the number of grams of each component to moles using <em>(n = mass / molar mass)</em>.

n of NOBr = (3.26 g / 109.8 g/mole) = 0.03 moles.

n of NO = (3.06 g / 29.9 g/mole) = 0.102 moles.

n of Br₂ = (8.15 g / 159.9 g/mole) = 0.051 moles.

Then we can get the concentration of each component by dividing its no. of moles by the volume of the vessel <em>(concentration = n / V)</em>.

The concentration of NOBr = (0.03 mole / 5.00 L) = 6x10⁻³ mol/L.

The concentration of NO = (0.102 mole / 5.00 L) = 2x10⁻² mol/L.

The concentration of Br₂ = (0.051 mole / 5.00 L) = 1x10⁻² mol/L.

Now, we can get Kc:

Kc = [NO]².[Br₂] / [NOBr]² = (2x10⁻² mol/L)².(1x10⁻² mol/L) / (6x10⁻³ mol/L)² = 0.122.

the temperature of a balloon rises from 275 degrees k to 395 degrees k, what would the ending volume be if it started at 5 L

Airida [17]

<h3>Answer:</h3>

7.182K

<h3>Explanation:</h3>

From the question we are given;

Initial temperature, T1 = 275 K
Final temperature, T2 = 395 K
Initial volume, V1 = 5 L

We are required to calculate the final volume, V2

Charles's law is the law that relates the volume of a gas and its temperature.
It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
Therefore;

$\frac{V1}{T1}=\frac{V2}{T2}$

To calculate, V2 we rearrange the formula;

$V2=\frac{V1T2}{T1}$

$V2=\frac{(5L)(395K)}{275}$

$V2=7.182K$

Therefore, the ending volume will be 7.182K
