Answer:

B - The atoms form a bond with a bond length of 75 pm

From the potential energy diagram of shown, we can infer that the atoms form a bond with a bond length of 75 pm.

When atoms are far away from each other, there exists no interaction whatsoever between the atoms.

However, as the atoms draw closer to each other, the potential energy diagram begins to shift towards an energy minima as we can see from the potential energy diagram.

As the system continues to tend towards this minima, the distance between the atoms decreases. The distance at which the two atoms have the lowest energy is called the bond length.

For this system, such a bond length occurs at 75pm as we can see from the diagram.

every mole of anything contains Avogodro's number of atoms.  So: 6.08x10^23 x 3.33 = ?

Explanation:

Answer:

30%

Explanation:

As the formula for finding concentration

= (mass of solute/mass of solution)×100

= (30/100)×100

= 0.3×100

= 30%

The concentration is 30%.

As the formula for finding concentration

= (mass of solute/mass of solution)×100

= (30/100)×100

= 0.3×100

= 30%

1. from      2. to

Explanation:

Answer:

In atomic physics and quantum chemistry , the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6, using the notation explained below.

Explanation:

i found it on google

Answer:

To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.

Explanation:

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.

Answer/Explanation:

Tentative means that something is uncertain. So if some aspect of science is described as "tentative" it probably means that there is some evidence to support a hypothesis, but there is more work to be done to be sure about the statements being made.

You may also see these reports described as "preliminary", as they are acknowledging the work is not complete

Answer:

Talc

Explanation:

Talc only has a hardness of one on the Moh's scale of hardness. This translates into a very soft material, which results from its layered nature. Naturally, this substance is hydrophobic (dislikes water), and tends not to absorb water, therefore giving some of its favourable water-resistant characteristics.

Answer:

The correct answer is A.

Explanation:

The acids with hydrogen atoms in them are the ones that dissolve best in water and when they do, they get diluted, raising their pH level by releasing hydrogen ions (H+) into the solutions.

So when acids get dissolved in water, positively charged hydrogen atoms are released.

The answer is A.

Answer:

D. The net electrical charge of the Earth.

Explanation:

I remember from middle school. The other three options affect the gravitational force.

The gravitational force between the earth and the sun is dependent on the mass of these two objects as well as the distance between the earth and the sun. Thus, option D is the correct answer.

Gravitational pull is referred as a force of attraction beared by the planetary objects. Gravity is responsible for the revolution of planets around the sun in their fixed orbits.

Gravitational pull is important as it keeps the earth revolving around the sun from a safe distance. It holds the earth in position and thus supports the life on earth. Gravity is responsible for optimum atmosphere on earth.

The formation of celestial bodies is also under the influence of gravitational pull. Gravitational force thus is consired as a fundamental force that govers all the celestial bodies.

Gravitational pull is therefore important for the life on earth.
