The ability of a substance to dissolve in another at a given temperature and pressure is: solubility

Here's my reasoning:

There are two things that make up a solution:

A solute and a solvent.

The solute gets dissolved into the solvent (most likely water).

If you need more info, just comment below. Good luck with your studies! :)

How many of grams of CuSO4 are in 475ml of a 2.0M aqueous solution

Anettt [7]

Answer:

151.63 g

Explanation:

We first get the number of moles;

Moles = Molarity × volume

= 2.0 × 0.475

= 0.95 moles

1 mole of CuSO4 = 159.609 g/mol

Therefore;

Mass = moles × molar mas

= 0.95 moles × 159.609 g/mol

= 151.63 g

What is the sequence in the formation of the Earth and the Universe?

Bezzdna [24]

Answer:

The Earth formed billions of years after the Universe formed

Explanation:

The "universe" is said to have been formed billions of year ago through an explosion. This was called the "Big Bang Theory." This lead to the expansion of the universe owing to its high temperature and density. After which, the universe cooled down. Galaxies and stars were then formed. Some of the stars died due to explosion, which then led to the creation of planets. Such formation of the planets happened around 4.5 billion years ago. This is 9.3 billions of years later than the universe was formed (13.8 billions of years ago). So, this explains the answer.

What does the rf value describe on a microscopic level why is this important?

lys-0071 [83]

Answer: The retention factor describes the rate at which a compound migrates on a microscopic level.

The retention factor (Value) serves as a simple measurement of the relative binding of the compound of interest under the experimental conditions.

Retention factor values are used in identification purposes;

• Use to determine the affinity of the solute to the solvent

• Greater retention factor means greater affinity of solute to the solvent
