What are electrons?

An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The charge on a single electron is considered the unit electrical charge.

Electrons are sub-atomic particles that occupy energy levels in an atom of any chemical element. These electrons may move from one energy level to another.

Electrons may move from a lower energy level or ground state to an excited state or high energy level, or else move from a higher energy level to a lower energy level.

When an electron moves from a lower energy level to a higher energy level energy is absorbed by the atom, and when the movement is from a higher energy level to lower energy is released mainly as light.

Hence, option A is correct.

Answers

The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.

In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.

During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.

if the column of water in the water barometer rose to a height of 39 feet, what would the atmospheric pressure be in mm hg?

Answers

The atmospheric pressure for a column of water barometer that rose to 39 feet is 874 mmHg

From the given information, to determine the atmospheric pressure at which the column of the water barometer rose, we will need to convert the height of the water column to mmHg.

From the dimensional analysis of standard rate conversion, we know that:

1 feet  = 12 inches

1 inch = 25.4 mm

1 mmHg = 13.6 mm of water.

[tex]\mathbf{\implies 39 \ feet \ of \ H_2O \times \dfrac{12 \ in ch \ H_2O}{1 \ feet \ H_2O} \times \dfrac{25.4 \ mm \ H_2O}{1 \ inch \ H_2O} \times \dfrac{1 mmHg}{13.6 \ mm \ H_2O}}[/tex]

Find the pOH for the following:

A 1.34 x 10^-4 M solution of hydrochloric acid.

A) 10.13

B) 3.87

C) 4

D) 10

Answers

Answer:

A) 10.13 is the answer

Explanation:

Since HCl is a strong acid, its pH can be found by simply plugging it into the equation:

pH = -log[H+]

*H+ is just the concentration you were given*

Now that you have the pH, you just subtract it from 14 to find the pOH

I have attatched my work below. Hope this helps! :^)

To find the pOH of a solution, you can use the formula: pOH = -log10[OH-]

What is pOH?

pOH is a measure of the concentration of hydroxide ions (OH-) in a solution. It is the negative logarithm (base 10) of the hydroxide ion concentration.

In this case, since we have hydrochloric acid (HCl), we need to consider the concentration of hydroxide ions (OH-) produced when HCl dissociates in water.

HCl is a strong acid and completely dissociates, meaning it produces an equal concentration of hydrogen ions (H+) and chloride ions (Cl-) in water. Since there are no hydroxide ions produced, the concentration of hydroxide ions is 0.

Therefore, the pOH of a hydrochloric acid solution is 0, and none of the options provided (A, B, C, D) is the correct answer.
