which sample, when dissolved in 1.0 liter of water, produces a solution with the highest boiling point?

Answers

Answer 1

Answer: After a thorough research, the same question exists with the following choices.

(1) 0.1 mole KI
(2) 0.2 mole KI
(3) 0.1 mole MgCl2
(4) 0.2 mole MgCl2

The correct answer is (4) 0.2 mole MgCl2. IN Vant Hoff factor, it is greater for MgCl2. There are more ions.

Answers

Answer : Option A) Dry media

Explanation : i) Dry media is a media that deposits graphite, charcoal, pastels, ordinary pencils, then moistened with a wet brush to get various painterly effects on the paper fibers.

ii) Silverpoint - Silverpoint media uses red chalk or traces of black pencil on white-coated paper usually the manuscripts,

iii) Ink Painting - Uses various inks on the paper.

iv) Liquid media - uses liquid pigments suspended in some base which in liquid state that soaks the paper.

A student neutralized 16.4 milliliters of HCl by adding 12.7 milliliters of 0.620 M KOH. What was the molarity of the HCl acid?(1) 0.168 M (3) 0.620 M
(2) 0.480 M (4) 0.801 M

Answers

The molarity of the HCl acid is 0.480 M. The correct option is 2.

What is molarity?

Molarity is the division of the mass of the solution to the volume of the solution.

The formula that is used is

$\rm M_1V_1= M_1V_2$

Putting the values in the equation

0.620 * 12.7 = M1 * 16.4 = 0.480

Thus, the molarity of the HCl acid is 2). 0.480 M.

#SPJ2

Molarity is equal to the moles of solute over liters of solvent. In getting the molarity of HCl, you must know the formula for two solutions which is equal to M1V1 = M2V2. (16.4 milliliters of HCl)M1 = (12.7 milliliters) (0.620 M KOH) and you have 0.480M HCl. The answer is number 2.

Answer:

Explanation:

The atoms of a certain material can absorb red and blue light frequencies. What happens to yellow light that shines on it? It is absorbed.
It is reflected.
It is transmitted.
It is either reflected or transmitted.

Answers

Answer: It is either reflected or transmitted.

Explanation:

The color of the objects is due to the light reflected to our eyes.The light falls on the surface of the object and the color which does not get absorbed by the object gets transmitted or reflected and thus appear to be of the same color as the reflected or transmitted light.

Example: If an object absorbs all of the frequencies of visible light except for the frequency associated with green light, then the object will appear green in color.

It is reflected ir transmitted depending on what the material is. The color that something appears is actually the color that it reflects or transmits and not the color that it absorbs. I hope this helps.
