For the reaction where Δn=−1Δn=−1 , what happens after in increase in volume? ????KQ>K so the reaction shifts toward reactant

Alex787 [66]

Answer:

Explanation:

In general, an increase in pressure (decrease in volume) favors the net reaction that decreases the total number of moles of gases, and a decrease in pressure (increase in volume) favors the net reaction that increases the total number of moles of gases.

Δn= b - a

Δn= moles of gaseous products - moles of gaseous reactants

Therefore, <u>after the increase in volume</u>:

If Δn= −1 ⇒ there are more moles of gaseous reactants than gaseous products. The equilibrium will be shifted towards the products, that is, from left to right, and K>Q.
If Δn= 0 ⇒ there is the same amount of gaseous moles, both in products and reactants. The system is at equilibrium and K=Q.
Δn= +1 ⇒ there are more moles of gaseous products than gaseous reactants. The equilibrium will be shifted towards the reactants, that is, from right to left, and K<Q.

Ugo [173]

The two resonating structures of Carbon Monoxide are shown below.
The movement of electrons are shown by arrow.

Structure A:
In structure a A the formal charges of Carbon and Oxygen are zero. As Formal Charge is calculated as,

= # of valence electron - electrons in lone pairs + 1/2 bonding electrons electrons

For C:
= 4 - 2 + 4/2
= 4- 4
= 0

For O:
= 6 - 4 + 4/2
= 6- 6
= 0

Structure B:

Formal Charge on C:

= 4 - 2 + 6/2
= 4- 5
= -1

Formal Charge on O:

= 6 - 2 + 6/2
= 6 - 5
= +1

What makes water so good at dissolving other things

Nina [5.8K]

Water molecules are polar. Water has the ability to dissolve a variety of different substances. Water dissolves more substances than any other liquid. Water has excellent chemical composition and physical attributes. This is why water is such a great solvent.

Hope this helps!
