Which of the following best describes a Lewis base?

Chemistry
2 answers:
Semenov [28]3 years ago
7 0

Answer: Option (C) is the correct answer.

Explanation:

According to Lewis, a base is a substance or specie which is able to donate electrons.

For example, NH_{3} is a lewis base because nitrogen has a lone pair of electron.

Therefore, when ammonia is dissolved in HCl it will accept the hydrogen atom as nitrogen gave electron to the hydrogen atom. As a result, hydrogen bonds with nitrogen atom.

             NH_{3} + HCl \rightarrow NH^{+}_{4}Cl^{-}  

Thus, we can conclude that it donates electrons in solution best describes a Lewis base.

What is the pH for a solution that has an OH ion
Basile [38]
Assuming that you mean 10^-4 M then this would be basic and would have a pH of 10.

pOH = -log[OH].
So pOH = 4
pH=14-pOH
pH = 10

Prove that PV = nRT.​
qaws [65]

Find your answer in the explanation below.

Explanation:

PV = nRT is called the ideal gas equation and its a combination of 3 laws; Charles' law, Boyle's law and Avogadro's law.

According to Boyle's law, at constant temperature, the volume of a gas is inversely proportional to the pressure. i.e V = 1/P

From, Charles' law, we have that volume is directly proportional to the absolute temperature of the gas at constant pressure. i.e V = T

Avogadro's law finally states that equal volume of all gases at the same temperature and pressure contain the same number of molecules. i.e V = n

Combining the 3 Laws together i.e equating volume in all 3 laws, we have

V = nT/P,

V = constant nT/P

(constant = general gas constant = R)

V = RnT/P

by bringing P to the LHS, we have,

PV = nRT.

jarptica [38.1K]

Answer:

The constant density decreases

Explanation:

As the temperature of a solvent increases, the solubility of any gas dissolved in that solvent decreases.

For example:

when the temperature of a river, lake or stream is raised high , due to discharge of hot water from some industrial process the solubility of the oxygen in the water is decreased .The fish and the other organisms that live in the water bodies such as rivers, ponds, lakes etc can survive only in the presence of oxygen and decrease in the concentration of the water due to increased temperature can lead to the death of the fish and this may in turn damage the ecosystem.

In the above example, water is considered as the solvent and the oxygen is considered as the solute. When the temperature of the solvent that is water increases, the solubility of the gas that is oxygen in the solvent decreases.

Therefore the answer is decreases
