Answer:

The expected student enrollment in 2003 is 1244.

Explanation:

The given diagram it is clear that the graph represents the relationship x and y, where x is number of years since 2000 and y is number of student enrollment.

From the given figure it is clear that the equation of best fit line is

$y=82x+998$ .... (1)

We need to find the expected student enrollment in 2003.

Year 2003 is 3 years since 2000.

Substitute x=3 in equation (1) to find the expected student enrollment in 2003.

$y=82(3)+998$

$y=246+998$

$y=1244$

Therefore the expected student enrollment in 2003 is 1244.

You are given two aqueous solutions with different ionic solutes (Solution A and Solution B). What if you are told that Solution

klio [65]

Answer:

Yes, it is possible. Let us consider an example of two solutions, that is, solution A having 20 percent mass RbCl (rubidium chloride) and solution B is having 15 percent by mass NaCl or sodium chloride.

It is found that solution A is having more concentration in comparison to solution B in terms of mass percent. The formula for mass percent is,

% by mass = mass of solute/mass of solution * 100

Now the formula for molality is,

Molality = weight of solute/molecular weight of solute * 1000/ weight of solvent in grams

Now molality of solution A is,

m = 20/121 * 1000/80 (molecular weight of RbCl is 121 grams per mole)

m = 2.07

Now the molality of solution B is,

m = 15/58.5 * 1000/85

m = 3.02

Therefore, in terms of molality, the solution B is having greater concentration (3.02) in comparison to solution A (2.07).

Calculate the ph of sweater which has a hydrogen ion concentration of 1 times 10 to the power of 8

telo118 [61]

Answer:

The pH of the sweater containing Hydrogen ion concentration

$[H^{+}]=1\times 10^{-8}$ is

8

Explanation:

pH = It is the negative logarithm of activity (concentration) of hydrogen ions.

pH = -log([H+])

Now, In the question the concentration of [H+] ions is :

$[H^{+}]=1\times 10^{-8}$

$pH = -log(1\times 10^{-8})$

use the relation:

$log(10^{-a})=a$

$pH= -(-8)$

pH = 8

Note : 1 times 10 to the power of 8 must be" 1 times 10 to the power of -8"

If the concentration is

$[H^{+}]=1\times 10^{8}$

Then pH = -8 , which is not possible . So in that case the pH calculation is by other method

Which of the following best explains why ionic crystals are brittle?

Natalka [10]

Packing

Explanation:

Ionic crystals are brittle due to the tight packing of their crystals. This provides little to no mobility between one another.

Brittleness implies having little to no elasticity.
Ionic crystals are held together by strong crystal lattice forces
These forces prevents crystals from freely rotating and moving space.
It holds them rigidly and fixed in place.
Ionic crystals are hard and held electrostatic forces.
