If 3.25 g N2 gas is introduced into an evacuated 1.50 L flask at 325 K, what is the pressure
Volgvan

Answer:

2.06 atm

Explanation:

The computation of the pressure inside the flask is shown below;

As per the ideal gas law

we know that

P V = nRT

where

V = 1.50L

T = 325 K

R = 0.0821

Now moles of N_2 is

= 3.25 ÷ 28

= 0.116 mol

Now

P = NRT ÷ V

= 0.116 × 0.0821 × 325 ÷ 1.50

= 2.06 atm

In what main way is separating the components of a mixture different from separating the components of a compound?
Zigmanuir [339]

Explanation:

Compounds are the species in which all the components react chemically to form a molecule which has a different property from the constituting elements.

On the other hand, mixture are the species in which the components do not react chemically and the original properties of the components are not lost.

<u>Thus, separation of the mixture into its components can be done by the physical means while separation of the compound into its components can be only possible by the chemical means.</u>

Hope this helps! :)
