Answer:

Particles form clouds with them.

Explanation:

The particles are removed from the atmosphere by dry and wet deposition processes. Dry deposition is produced when the wind carries these particles and makes them hit an obstacle. While wet, the particles serve as small condensation nuclei to form clouds, on which water or ice accumulates.

Katarina [22]

Answer:

(S)-3-methoxy-3-methylbutan-2-ol

Explanation:

In this case, we have an epoxide opening in acid medium. The first step then is the protonation of the oxygen. Then the epoxide is broken to generate the most stable carbocation. The nucleophile ( $CH_3OH$ ) will attack the carbocation generating a new bond. Finally, the oxygen is deprotonated to obtain an ether functional group and we will obtain the molecule (S)-3-methoxy-3-methylbutan-2-ol.

Which one of the following compounds will NOT be soluble in water? Which one of the following compounds will NOT be soluble in w

Nadusha1986 [10]

Answer:

$BaSO_{4}$ will be not soluble in water

Explanation:

LiOH is a strong base. Hence it gets completely dissociated in aqueous solution.

$NaNO_{3}$ is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.

$MgCl_{2}$ is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.

$K_{2}S$ is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.

$BaSO_{4}$ is a sparingly soluble salt. Hence it is not dissociated and hence dissolved in water. This is due to the fact that both $Ba^{2+}$ and $SO_{4}^{2-}$ ions are similar in size. Hence crystal structure of $BaSO_{4}$ is quite stable. Hence $BaSO_{4}$ is reluctant to undergo any dissociation in aqueous solution.

If I have 340 mL of a 0.5 M NaBr solution, what will the concentration be if I add

Charra [1.4K]

Answer:

Option C. 0.23 molar

Explanation:

The following data were obtained from the question given:

C1 = 0.5 M

V1 = 340mL

V2 = since 400mL was added to the original volume, therefore = 340 + 400 = 740mL

C2 =?

The concentration of the diluted solution can be calculated by using the following:

C1V1 = C2V2

0.5 x 340 = C2 x 740

Divide both side by 740

C2 = (0.5 x 340) / 740

C2 = 0.23M

Therefore, the new concentration of the solution is 0.23M
