There are 20.8 moles of propanol

Further explanation  

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

1.2 x 10⁵ molecules of propanol

Show Your Work

Answers

Answer:

P = 34.1 L

Explanation:

Given data:

Number of moles = 10 mol

Volume occupy = 15 L

Temperature = 350°C

Pressure of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

350+273 = 623 K

by putting values,

P×15 L = 10 mol ×0.0821 atm.L/ mol.K ×623 K

P = 511.48atm.L/15L

P = 34.1 L

Green light has a frequency of 6.01x10^14Hz what is the wavelength

Answers

Answer:

λ  = 0.5×10⁻⁶ m

Explanation:

Given data:

Frequency of light = 6.01 ×10¹⁴ Hz

Wavelength of light = ?

Solution:

Formula:

Speed of light = wavelength × frequency

Speed of light = 3×10⁸ m/s

3×10⁸ m/s = λ × 6.01 ×10¹⁴ Hz

λ  = 3×10⁸ m/s / 6.01 ×10¹⁴ Hz

        Hz = 1/s

λ  = 0.5×10⁻⁶ m

Which method of heat transfer is the person in the picture below most worried about?

Radiation

Conduction

Convection

Answers

Answer:

Radiation ...........

Hey There!_____________________________________Answer:

[tex]\huge\boxed{Conduction}[/tex]

_____________________________________Conduction:

Conduction is the transfer of heat when two things come in contact with each other. The energy transfer is from hotter body to the colder body.

                                x---------------------------------------------x

Fire Walking:

There is a trick behind fire-walking. When the coal burns, after sometime there is a layer of ash on the surface of the coal which blocks the radiation. So the transfer of heat is not possible from radiation. Conduction is the only way possible. The person's feet and coal both are poor conductor of heat so if we walk quickly i.e. there is minimal time of contact with the coal, it will just feel a little warm. As the person start walking on the coal, It has to do it quickly, that way Person will feel its sole warming up but it is not that hot because of the layer of ash and poor conductance, after few steps the ash also sticks on to the sole of the person which makes kind of double layers of ash. So the only way for heat transfer is CONDUCTION.

D dark colors absorb the sun more cause the wants to make everything bright I hope I helped :)

The statement " Darker colors absorb more energy from electromagnetic waves than lighter colors do." is correct.

What is electromagnetic waves?

When an electric field collides with a magnetic field, electromagnetic waves are created. As a result, they're called electromagnetic waves.

What is light?

Light, often known as visible light, is electromagnetic radiation that falls within the region of electromagnetic wave or spectrum that the human eye can perceive.

White is a mixture of all seven colors found in the white light spectrum, including Violet, Indigo, Blue, Green, Yellow, Orange, and Red. This visible spectrum has a wavelength of 400 to 700 nanometers. When an object appears to be a particular color, such as red, it signifies that it is projecting the wavelength of red light  (620 to 750 nanometers) while absorbing all other wavelengths. Furthermore, because  light is a kind of energy, the more light a thing consumes, the more heat it consumes.
