Which intermolecular force depends on the formation of temporary dipoles?

Chemistry
1 answer:
aliya0001 [1]3 years ago
3 0

Correct answer: C) dispersion forces

Dispersion forces are the intermolecular forces of attraction present in all types of molecules. These are the weakest forces of attraction in which atoms of the molecule align in such a way that weak forces of attraction develop between electron cloud of one atom and the positively charged nucleus of the adjacent atom. This is referred to as induced dipole-induced dipole type of interaction. Therefore in dispersion forces temporary dipoles are developed due to constant motion of electrons that results in asymmetric electron distribution around the nucleus in an atom.

How does the water cycle ensure that we have water
Romashka-Z-Leto [24]
The water cycle does not ensure that we have water. We must HAVE water to cause water cycle. 

Evaporation, then condensation, and finally precipitation.
This would happen in order.

Hope this helps!

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.

To what volume (in mL) would you need to dilute 25.0mL of a 1.45 m solution of Kcl to make a 0.0245m solution of KCl
dezoksy [38]

Answer:

The answer is

<h2>1479.60 mL</h2>

Explanation:

In order to calculate the volume needed we use the formula

V_2 =  \frac{C_1V_1}{C_2}

where

C1 is the concentration of the stock solution

V1 is the volume of the stock solution

C2 is the concentration of the diluted solution

V2 is the volume of thevdiluted solution

From the question

C1 = 1.45 M

V1 = 25 mL

C2 = 0.0245 M

So we have

V_2 =  \frac{1.45 \times 25}{0.0245}   =  \frac{36.25}{0.0245}  \\  = 1479.59...

We have the final answer as

<h3>1479.60 mL</h3>

Hope this helps you
