Answer:

Explanation:

Given parameters:

Volume of solution = 575mL

Concentration of solution = 0.9M

New volume = 1.25L

Unknown:

New concentration = ?

Solution:

Since the number of moles remains the same, we can use this parameter to solve the problem given.

Concentration = $\frac{number of moles}{volume}$

Number of moles of solution before diluting = concentration x volume

Number of moles = 0.9 x 575 x $\frac{1}{1000}$ = 1.565 moles

New concentration = $\frac{number of moles }{volume}$ = $\frac{1.565}{1.25}$ = 1.25M

rewona [7]

Answer:

b. The amount of SO3(g) decreases and the value for K increases.

Explanation:

Hello,

In this case, for the given reaction:

$2SO_2(g) + O_2(g)\rightleftharpoons 2SO_3(g)$

The change in the stoichiometric coefficient is:

$\Delta \nu=2-2-1=-1$

In such a way, since the reagents have more moles than the products, based on Le Chatelier's principle, if the volume is increased, the side with more moles is favored. In addition, since the formation of reagent is favored, K is diminished based on the law of mass action shown below:

$K=\frac{[SO_3]_{eq}^2}{[SO_2]_{eq}^2[O_2]_{eq}}$

Therefore the answer is:

b. The amount of SO3(g) decreases and the value for K increases.

Best regards.

How many moles of KClO3 are needed to produce 480 grams of O2?

gayaneshka [121]

Answer:

2:3

You'd need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 3/2 times more moles of the latter.
