At what temperature (in K) will 3.5 moles of gas occupy 2.7 L at 1.5 atm? HELP PLEASE!

Vesnalui [34]

3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K

IDEAL GAS LAW:

The temperature of a gas can be calculated using the ideal gas law equation:

PV = nRT

Where;

P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)

According to this question, P = 1.5atm, V = 2.7L, n = 3.5moles, T = ?

1.5 × 2.7 = 3.5 × 0.0821 × T

4.05 = 0.28735T

T = 4.05 ÷ 0.28735

T = 14.1K

Therefore, 3.5 moles of a gas will occupy 2.7 L at 1.5 atm at a temperature of 14.1K

Which quantity is equivalent to the product of the absolute index of refraction of water and the speed of light in water?

givi [52]

The quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

<h3>What is the speed of light?</h3>

Speed of light is the rate of speed though the light travels. To find the speed of light in any medium, the following formula is used.

$v=\dfrac{c}{n}$

Here, (n) is the index of reaction and (c) is the speed of light in the vacuum. The speed of light in the vacuum is almost equal to the 3.0×10⁸ m/s.

Now the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water has to be find out.

The above formula can be written as,

$v=\dfrac{c}{n}\\vn=c\\c=vn$

Here, the product of index of refraction and speed of light is equal to the speed of light in vacuum. This will be true for water as well.

Thus, the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

Write the electron configuration for sodium.

Dafna11 [192]

Answer:

1s^2..2s^2..2p^6..3s^1

Explanation:

Since sodium has 11 electrons...its electron configuration is...;

1s^2..2s^2..2p^6..3s^1

;The powers of the energy levels(i.e s,p,d) should all add up to the number of electrons in an atom

*.When writing...please do not separate them.
