If the colored spheres are solutes, the overall direction of water would be out of the cell based on the principle of osmosis.

<h3>What is osmosis</h3>

It is the movement of water molecules from the region of high water potential (low solutes) to the region of low water potential (high solute) through a selectively permeable membrane.

In the illustration, there are more colored spheres outside of the cell than inside of it. This means that there are more solutes outside the cell (lower water potential) than inside of the cell (higher water potential).

Thus, water will move from the inside of the cell to the outside until an equilibrium is established.

The most common cooling mechanism for cloud formation is ________.

KatRina [158]

The answer is "Rising and expanding air or atmosphere cooling".
To form a cloud the air must be cooled to the temperature of dew point. when there is expansion of air, it cools to the dew point and thus the formation of cloud happens. This process is very common and used for the formation of clouds.

If a mass of a cube were 48.0g and its volume 24.0 cm3 what would its density be

EastWind [94]

Answer:

<h3>The answer is 2 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 48 g

volume = 24 cm³

We have

$density = \frac{48}{24} \\$

We have the final answer as

Calculate the hydroxide ion concentration of a 0.200 M solution of HCIO4

Aleksandr [31]

The concentration of hydroxide ion is 5 $\times$ 10^ − 14 M.

<u>Explanation:</u>

Consider the equilibrium of this acid's dissociation,

H C l O 4 ⇌ H + + C l O 4 -

Moreover, let's assume that H C l O 4 is a strong acid and will fully dissociate.

Hence,

[ H + ] = 0.20 M

Now, recall,

K w = [ H + ] [ O H − ] = 1.0 $\times$ 10 ^− 14

Hence,

⇒ [ O H − ] = K w / [ H + ] = 5 $\times$ 10^ − 14 M.
