how does molecule movement in solids and liquids differ​

Answers

Answer 1
Solids are well.. Solid. Meaning they are a harder object than liquid. Liquid is less controlled and moves a lot more.

A _____ state is when the electron is closest to the nucleus.

Answers

Answer:

ground state

Explanation:

A ground state is when the electron is closest to the nucleus.

What is the ground state of an atom?

The ground state of an electron is the state of the lowest energy for that electron. The nucleus is surrounded by electrons that occupy orbitals of varying energy levels.

When an electron jumps to an energy state greater than its ground state, then it is in an excited state. An electron can become excited from the ground state to the excited state if it is given extra energy in the form of a photon, or packet of light.

An electron occupies the lowest energy level that is closer to the nucleus when the electron is present in the ground state.

What is the total mass?

Answers

Answer:

[tex]\boxed {\tt 48 \ grams}[/tex]

Explanation:

Mass can be found by multiplying the density by the volume.

[tex]m=d*v[/tex]

The density is 2 grams per cubic centimeter.

The volume is 24 cubic centimeter.

[tex]d= 2 \ g/cm^3 \\v=24 \ cm^3[/tex]

Substitute the values into the formula.

[tex]m= 2 \ g/cm^3 *24 \ cm^3[/tex]

Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.

[tex]m= 2 \ g * 24[/tex]

[tex]m= 48 \ g[/tex]

The mass of the material is 48 grams.

If you have 128 atoms of a radioactive substance, with a half-life of 31 seconds, how many atoms would remain after 62 seconds? Please show your work.

Answers

Answer:

N = 32 atoms

Explanation:

The radioactive elements decays as follows:

Ln (N/N₀) = -kt

Where N are number of atoms after t time, N₀ are initial number of atoms, k is decay constant in time⁻¹

We can obtain k from t(1/2):

k = ln 2 / t(1/2)

k = 0.02236s⁻¹

Ln (N/128 atoms) = -0.02236s⁻¹*62s

(N/128 atoms) = e^-1.386

N/128 atoms = 0.25

N = 128 atoms * 0.25

N = 32 atoms

how to draw Bohr Model of Phosphorus?? ​

Answers

Answer:

look at the image below

Explanation:

The Bohr model of phosphorus depicts 15 electrons in different energy levels, with the nucleus at the center.

Two electrons are present in the first energy level, eight electrons are present in the second and five electrons are present in the third. The electron configuration of phosphorus, which is [tex]1s^2 2s^2 2p^6 3s^2 3p^3[/tex], matches this distribution.

The formula [tex]2n^2[/tex], where n is the energy level number, determines the maximum number of electrons in each energy level. Therefore, the first energy level can accommodate only two electrons, the second energy level up to eight, and the third energy level up to eighteen.

5.
If 6.5 g of magnesium ribbon reacts completely
with hydrochloric acid, how many grams of
hydrogen gas would be liberated? Mg , + 2HC1(ag)
→ MgC1 + H, [H = 1.0, Mg = 24.0]

Answers

Answer:

The mass of hydrogen gas liberated is 0.6 g.

Explanation:

Given data:

Mass of Mg = 6.5 g

Mass of hydrogen gas liberated = ?

Solution:

Chemical equation:

Mg + 2HCl     →    MgCl₂ + H₂

Now we will calculate the number of moles of Mg.

Number of moles = mass / molar mass

Number of moles = 6.5 g/ 24 g/mol

Number of moles = 0.3 mol

Now we will compare the moles of Mg with hydrogen gas.

            Mg         :          H₂

             1           :           1

             0.3       :        0.3

Mass of H₂:

Mass = number of moles × molar mass

Mass = 0.3 mol × 2 g/mol

Mass = 0.6 g

Which conclusion about the chemical reactivity of these elements is valid? Boron is the most reactive because it has the most protons. Fluorine is the most reactive because it has 7 electrons in the outer shell. Silicon is the most reactive because it has an equal number of protons and neutrons. Gallium is the most reactive because it has many more neutrons than protons.

Answers

Answer:

Fluorine is the most reactive because it has 7 electrons in the outer shell. The conclusion of this element's chemical reactivity is valid .

Explanation:

Among all the given elements - Boron ,Fluorine , Silicon and Gallium , Fluorine is the most reactive element because it has 7 electrons in the outer shell. It has a very small size and only requires one electron to get into a stable configuration with that of noble gases. Thus, to reach that stable state, they react spontaneously with elements, leading to its high reactivity.

Therefore, most reactive elements are in the halogen band, and none of the other three elements called Boron, Silicon and Gallium belong to the halogen group.

Hence, the correct answer is B (fluorine is the most reactive because it has 7 electrons in the outer shell).

Susan made observations about outside events she noticed throughout the day. The day began with rain. Susan saw puddles on the road. The rain stopped and the sun began to shine. The puddles disappeared. Later, clouds began to form in the sky. How do the parts of the water cycle relate to the events that Susan saw?

Answers

Answer:

Rainfall - precipitation

disappeared puddles - evaporation

cloud formation - condensation

Explanation:

Rainfall that is observed by the Susan is the precipitation of the water cycle in which the water vapor that was condensed become heavy and form droplets of water and fall from sky to the earth surface.

Puddles that formed due to rainfall are the collection of water in the water cycle which is evaporated (process: evaporation) into the atmosphere n the form of water vapor which condensed to form clouds.
