Answer:

The chemical equilibrium of the system will be unaffected. The chemical equilibrium of the system will shift to the right to favor the forward reaction. The chemical equilibrium of the system will shift to the left to favor the reverse reaction. (I hope this helped!!)

CHEMISTRY QUESTION

daser333 [38]

Electronegativity of an element refers to its tendency to attract a pair of electrons towards itself.

An ionic bond is formed by the complete transfer of electrons from one element to the other. This implies that the combining elements should exhibit a large difference in their electronegativity values.

In contrast, a covalent bond is formed by a mutual sharing of electrons between 2 atoms that do not differ much in their electronegativity values.

Given Electronegativity values are:

A = 0.75

B = 3.2

C = 3.7

a) The difference in electronegativity is the greatest between A and C i.e. 3.7 - 0.75 = 2.95. Hence, AC will form an ionic bond

b) The difference is least between B and C i.e. 3.7 -3.2 = 0.5. Hence, BC will form a covalent bond

c) In AC, C is more electronegative than A

C = anion and A = cation

The concentration of a biomolecule inside a rod‑shaped prokaryotic cell is 0.0035 M . Calculate the number of molecules inside t

timama [110]

Answer: This rod-shape prokaryotic cell has 3.740,734725‬ molecules

Explanation:

<u>Step 1 :</u> given data

Molarity of the prokaryotic cell = 0.0035 M

Length of the cell = 4.2 μm = 4.2 * 10^-6 m

diameter of the cell = 1.3 μm = 1.3 * 10^-6 m

<u>Step 2: </u>calculate volume

To calculate volume of a rod, weneef to know the radius.

V = r ² × l

The radius = half of the diameter : r = d/2 ⇒ (1.3 * 10^-6 m)/2 = 0.65 * 10^-6 m

V= (0.65 * 10^-6 m)² * 4.2 * 10^-6 m = 1.7745 * 10 ^-18 L

<u>Step 3:</u> Calculating number of moles

Number of moles = Concentration * Volume

moles = 0.0035 M * 1.7745 * 10 ^-18 L = 6.21075 * 10^-21 moles‬

<u>Step 4:</u> calculating number of molecules

1 mole contains 6.023 * 10 ^-23 molecules

6.21075 * 10^-21 moles contain : 6.21075 * 10^-21 * 6.023 * 10 ^-23 molecules = 3.740,734725‬ molecules

This rod-shape prokaryotic cell has 3.740,734725‬ molecules

What is the name for the negative subatomic particles in an atom?

netineya [11]

Particles which are much smaller than atoms are known as subatomic particles. Neutrons, protons, and electrons are subatomic particles. Neutrons are neutral, protons are positively charged, and electrons are negatively charged particles

Hence, the name for a negative subatomic particle in an atom is an electron.

Thyroid hormone contains the mineral thyroid hormone contains the ________.

erica [24]

Thyroid hormone contains the mineral iodine (option I). Details about thyroid hormone can be found below.

<h3>What is the thyroid hormone?</h3>

Thyroid hormone is the hormone produced by the thyroid gland of the body, which is a large butterfly-shaped endocrine gland situated on the front of the neck that produces various hormones.

The thyroid hormone is responsible for regulating metabolism, which controls the amount of calories burnt in a day.

One of the major minerals found in the thyroid is iodine. The thyroid gland absorbs iodine from the bloodstream, and then stores it to aid in the production of thyroid hormones.

Therefore, the thyroid hormone contains the mineral iodine.
