the molar solubility of x2s in pure water us 0.0395

Answers

The Ksp shows the extent of dissolution of a solute in solution. The Ksp of the solution is 2.5 * 10^-4.

What is Ksp?

The Ksp is an equilibrium constant that is usd to show the extent of solubility of a solute in solution.

The equation for the solution of X2S is;

X2S(s) ⇄2X^+(aq) + S^2-(aq)

Ksp = [2s]^2 [s]

Since s =  0.0395 M

Ksp = 4s^3

Ksp = 4[0.0395 ]^3

Ksp = 2.5 * 10^-4

Which of the following aqueous solutions will have a pH that is significantly different from the rest?


0.1 M H 2SO 4


0.1 M HNO 3


0.1 M HC 2H 3O 2


0.1 M HCl

Answers

Among the given aqueous solutions, the solution with a significantly different pH from the rest is 0.1 M HC₂H₃O₂ (acetic acid).Option C

H₂SO₄ (sulfuric acid), HNO₃ (nitric acid), and HCl (hydrochloric acid) are strong acids that dissociate completely in water. They produce a high concentration of H₃O⁺ ions, resulting in a low pH. Acetic acid, on the other hand, is a weak acid that only partially dissociates in water. It produces a smaller concentration of H₃O⁺ ions, resulting in a higher pH compared to the strong acids.

When a strong acid like HCl, H₂SO₄, or HNO₃ is dissolved in water, it completely dissociates to release H₃O⁺ ions. The resulting solution will have a very low pH, usually close to 0. However, acetic acid (HC₂H₃O₂) only partially dissociates, and the concentration of H₃O⁺ ions is lower. As a weak acid, it has a higher pH compared to strong acids, typically around 2.4.

In summary, among the given options, the aqueous solution of 0.1 M HC₂H₃O₂ (acetic acid) will have a significantly different pH from the rest, with a higher pH value due to its weak acid nature.

Option C

Which describes isotopes? check all that apply. isotopes have the same atomic mass. isotopes have the same atomic number. isotopes are always stable. isotopes are always radioactive. isotopes are stable or radioactive. isotopes have different mass numbers.

Answers

Answer:

See below

Explanation:

Isotopes:

are atoms of the same element.have same number of electrons and protons.have different number of neutrons.have same atomic number.have different mass number.are either stable or reactive.

Example:

Hydrogen has three isotopes, protium, deutrium and tritium.Chlorine has two isotopes, Chlorine-35 and chlorine-37.

[tex]\rule[225]{225}{2}[/tex]

Any group of an element's isotopes will always contain an equal amount of protons and electrons. Their individual nuclei's capacity for holding neutrons will vary. The correct options are B, D, and F.

A set of atoms with the same atomic number but differing masses is known as an element's isotope. This indicates that the number of protons in each atomic nucleus and the number of electrons in the electron cloud of each isotope of an element is the same.

Some isotopes experience radioactive decay because of their unstable atomic nucleus. These isotopes are known as radioisotopes (or radionuclides) because they are radioactive by nature. Carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238 are a few examples of radioactive isotopes.

Thus the correct options are B, D, and F.

Answer:

The motion of the gas particles is random and in a straight-line.

Explanation:

According to the kinetic hypothesis, a gas is made up of a huge number of submicroscopic particles (atoms or molecules) that are all in continual, random motion. The swiftly moving particles clash with one another and with the container's walls on a regular basis. The phrase ideal gas refers to a hypothetical gas made up of molecules that adhere to a few rules: The molecules of an ideal gas do neither attract or repel one another. The sole interaction between perfect gas molecules would be an elastic collision when they collided or an elastic collision with the container's walls.

The pH of a solution prepared by dissolving 0. 350 mol of solid methylamine hydrochloride (CH3NH3Cl) in 1. 00 L of 1. 10 M methylamine (CH3NH2) is ________. The Kb for methylamine is 4. 40 ⋅ 10-4. (Assume the final volume is 1. 00 L. )

Answers

For the pH of a solution prepared by dissolving 0. 350 mol of solid methylamine hydrochloride, the pH is mathematically given as

pH = 11.14

What is the pH value of a solution prepared by dissolving 0. 350 mol ?

Generally, the equation for the pKb  is mathematically given as

pKb = -logKb

Therefore

pKb of CH3NH2 = -log(4.40×10-4)

pKb of CH3NH2= 3.36

Hence

pKa= 14 - pKb

pKa= 14 - 3.36

pKa= 10.64

In conclusion, using

pH = pKa + log([A-]/[HA])

pH = 10.64 + log(1.10M/0.350M)

pH = 11.14

You should answer in terms of electrons.

Down the group, the no. Of electron shells increases, and the distance between the nucleus and valance electrons increases. hence the attraction between the nucleus and valance electrons weakens. For metals, they have a tendency to lose electrons, and since down the group the attraction weakens, it is easier to lose electrons and hence it is more reactive.

If a solute has really strong bonds between its particles, would you expect it to form a solution that gets hold or cold? Explain your reasoning.

Answers

Answer:

The temperature of the solute/solvent without any external effect would decrease.

Explanation:

As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.

In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.

Answers

Answer:

The correct answer is A and D.

Explanation:

Please I want brainliest.

Reason:

The size of the ions follows the order:

Negatively charged ion > Neutral atom >

Positively charged ion

This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.

This happens due to the increase in

electron-electron repulsion.

Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.

Thus the size of the positively charged ion is least.
