Answer:

The cell is in a Hypotonic solution. When a cell is in a Hypotonic solution the lower osmotic pressure causing water to move across the pressure gradient into the solution causing the cell to shrivel.

Would the molecules in a gas have more or less movement than the molecules in a solid ? PLEASE HELP WILL MARK BRAINLY

Sergeeva-Olga [200]

Molecules in a gas will have more movement than molecules in a solid. This is because the molecules in solid matter are packed very tightly together to maintain its shape, whereas with gases they are spaced much further apart and fairly free to move. Hope this helps!

How the molecule’s properties affect the physical properties of a molecule

Lilit [14]

The intermolecular forces, such as hydrogen bonds or van der Waals attractions, which draw one molecule to its neighbors, govern a substance's physical properties. Due to the relatively weak intermolecular forces of attraction, molecular substances typically take the form of gases, liquids, or low melting point solids.

<h3>How do the intermolecular forces affect physical properties?</h3>

The forces that bind two molecules together are known as intermolecular forces. Intermolecular forces have an impact on physical properties. Strong and weak forces both exist; the stronger the force, the more energy is needed to separate the molecules from one another. As intermolecular forces increase melting, boiling, and freezing points rise.

The following intermolecular forces are listed in order of strength:

Van der Waals dispersion forces
Van der Waals dipole-dipole interactions
Hydrogen bonding
Ionic bonds

It would take very little energy to separate two molecules if they are connected by van der Waals dispersion forces. On the other hand, it requires a lot more energy to separate two molecules that are joined together by ionic bonds.

While conducting a lab experiment, Ali calculated that 1.20 E6 Joules of heat were needed to melt 18.5 kilograms of an unknown s

nordsb [41]

Answer:

Latent heat of fusion of the substance is $6.49\times 10^{4}J/kg$

Explanation:

Latent heat of fusion denotes amount of energy (heat) per unit mass required to melt a solid material at constant temperature and pressure i.e. at it's melting point

Here amount of heat required = $1.20\times 10^{6}J$

Mass of unknown substance being melted = 18.5 kg

So, latent heat of fusion of the substance = (required heat energy to melt)/(mass of the unknown substance) = $\frac{1.20\times 10^{6}}{18.5}J/kg=6.49\times 10^{4}J/kg$

So, latent heat of fusion of the substance is $6.49\times 10^{4}J/kg$

List the symbols for all the elements with electron configurations that end as follows. Each n represents an energy level.

Gwar [14]

List the symbols for all the elements with electron configurations that end as follows. Each n represents an energy level.

a. ns1

b. ns2np4

Answer: a) H, Li, Na, K, Rb, Cs, and Fr

b) O, S, Se, Te, Po

Explanation:

a. Determining the elements correlating to the electron configuration of "ns1" , you should understand that this suggests that the elements are in Group 1A.

This is because that there is one electron in an s-orbital. The orbital is located in the first column of the periodic table.

Thus, the elements that have this electron configuration are H, Li, Na, K, Rb, Cs, and Fr.

b. Determining the elements correlating to the electron configuration of ns^2np^4 characterizes group 6A of the periodic table.

This is because that there is have six valence electrons in their highest-energy orbitals (ns2np4). The orbital is located in the first column of the periodic table.

Thus, the elements that have this electron configuration are the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po).
