Chemistry

Delicious77 [7]1 year ago
3 0

The mole fraction of sulfur trioxide in the equilibrium mixture is 0.353.
Hence option (B) is the correct answer.

<h3>What is mole fraction ?</h3>

The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.

We have to use algebra here,

Because in the equation O_2 has a stoichometry of 1, the other have 2,

let O_2 = x

You started with 2 moles, so the moles of O_2 at equilibrium will be 2 - X

SO_3 has a stoichiometry of 2 compared to O_2, so will be 2X

( not minus from anything as you started with no moles of SO_3)

And then SO_2  will also be 2X as it’s stoichiometry is 2, but as you started with 2 moles it will be 2-2X

If you add these in an equation to get total moles it’s

2 - 2X  +  2 - X + 2X = 3.4 (total given)

and then gathering together becomes 4-X = 3.4

so,

4 = 3.4 + X

so,

x = 0.6

Therefore,

the moles of SO_3  = 2 x 0.6 = 1.2

mole fraction = moles of the gas / total moles of gas

mole fraction = 1.2 / 3.4 = 0.353

How are atoms of the same element with different mass numbers called?
ELEN [110]

Answer:

Isotopes

Explanation:

Isotopes are the same element with different masses because of the different number of neutrons. Also, the element doesn't change. If we change the protons, the element will change and then it won't be an isotope. Hope it helps!

ASAP Which of these mixtures would best be separated through distillation?
sveta [45]

Answer:

Water and acetone is best by separated through distillation

The correct answer would be option C Acetone and water.

Explanation:

When in a mixture of fluid solution, two liquids are mixed in a form of mixture then these liquid can be separated only one method which is based on the fact. That two different liquids will have two different boiling temperatures which method of separating the Fluids is distillation.  

The different liquids that are  present in mixture are boiled and the vapours are condensed and the condensed portion is  accumulated in another beaker.
