Answer:

To obtain a desired component from the mixture

Explanation:

It is also important to be able to separate mixtures to be able to better understand how each component contributes to the properties, chemical and physical, of the resulting mixture.

Answer:

Option a . 0.154L

Explanation:

P₁ . V₁ = P₂ . V₂

when we have constant temperature and constant moles for a certain gas.

At sea level, pressure is 1 atm so:

0.5 L . 1atm = V₂ . 3.25 atm

(0.5L . 1atm) / 3.25 atm = 0.154 L

Answer:

2.73 is the equilibrium constant for the dissociation of $F_2$ gas at 840 degree Celsius.

Explanation:

$F_2(g)\rightleftharpoons 2F(g)$

Initial

0.600 atm 0

Equilibrium

(0.600 atm - p) 2p

Total pressure at equilibrium = P = 0.984 atm

P= 0.600 atm - p)+2p=0.984 atm

p = 0.384 atm

Partial pressure of the $F_2$ gas , $p_{f_2}$ = (0.600 atm - 0.384 atm)=0.216 atm

Partial pressure of the $F$ gas, $p_{f}$ = 2(0.384 atm)=0.768 atm

$K_p=\frac{(p_{F})^2}{p_{F_2}}$

$K_p=\frac{(0.768 atm)^2}{0.216 atm}=2.73$

2.73 is the equilibrium constant for the dissociation of $F_2$ gas at 840 degree Celsius.
