The equilibrium constant is a special value of the reaction _________ that occurs when reactant and product concentrations are at their _____________ values.

The Gay Lussac’s formula is as follows :

P₁ / T₁ = P₂ / T₂

The Gay-Lussac law provides the relationship between the temperature and the pressure at the constant volume. This law states that at the constant volume, the pressure of the gas will be directly proportional to the temperature for the given gas.

If we heat up the gas, the molecules will be provide the more energy, and they move faster. If we cool down the molecules, they will be slow down and the pressure will decreases. The change in the temperature and the pressure can be calculated by using the Gay-Lussac law and it is as follows :

P ∝ T

P / T = k₁

P₁ / T₁ = P₂ / T₂

Where

P is the pressure of the gas

T is the temperature of the gas in Kelvin.

As a result, for a host atom with radius R, the size of an interstitial site for FCC is roughly 1.4 times that of BCC.

The steric number of octahedral molecules is equal to six since there are no lone electron pairs and six atoms are linked to the central atom. Octahedral molecules have an overall structure of eight interconnected triangles due to the creation of the surrounding atoms.

Tetrahedral holes are just about half as big as octahedral holes. An octahedral hole can accommodate an atom with a radius that is 0.414 times larger than the hole's constituent atoms. Tetrahedralness is consequently determined by the proportion of small to large atoms or ions that make up a crystal.

Heat transfers from object A to object B, because molecules from A collide with those from B. Option 1.

Heat always flows from an object at a higher temperature to an object at a lower temperature. When two objects at different temperatures are in contact with each other, their molecules collide, and this collision transfers energy from the hotter object to the colder object.

As a result, the hotter object loses heat, and the colder object gains heat. This process will continue until the two objects reach thermal equilibrium, meaning that they have the same temperature and there is no more net heat transfer between them.

Therefore, in the given scenario, object A, which is hotter, will transfer heat to object B, which is colder, as the molecules from object A collide with those from object B.

The molality of the solution that contains 16.32 g of glucose is calculated as 0.180 m.

Molality can be defined as number of moles of solute per kilogram of solvent. To find the molality of the solution, we need to calculate number of moles of glucose and the mass of the solvent.

Molar mass of glucose (C6H12O6) is: 6 x 12.01 + 12 x 1.01 + 6 x 16.00 = 180.18 g/mol

Number of moles of glucose is: n = m / M = 16.32 g / 180.18 g/mol = 0.0905 mol

Mass of water is 505.0 g.

The molality is: molality = moles of solute / mass of solvent in kg

mass of solvent = 505.0 g = 0.5050 kg

molality = 0.0905 mol / 0.5050 kg = 0.1795 mol/kg

molality = 0.180 m

Water is an important molecule because it can form hydrogen bonds, which allow it to have unique properties such as high heat capacity and being an excellent solvent for many substances.

It is not non-polar and is actually considered a polar molecule. Water is an important molecule because it can form hydrogen bonds due to its polar nature, which makes it an excellent solvent for a wide range of polar and ionic substances. Its high heat capacity enables it to absorb and release heat slowly, making it an effective temperature regulator in living organisms and the environment.

The final temperature of the water is 308 K.

To find the final temperature of the water, we need to use the formula Q = mcΔT, where Q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. The heat lost by the iron will be equal to the heat gained by the water, so we can set the equations equal to each other and solve for the final temperature.

  Qiron = Qwater

Heat lost by iron:

  Q = iron mass x specific heat of iron x temperature of iron

      = 25 x 0.449 x (398 - T)

Heat gained by water:

  Q = water mass x specific heat of water x temperature of water

      = 25 x 4.18 x (T - 298)

Since heat lost = heat gained, therefore:

  25 x 0.449 x (398 - T) = 25 x 4.18 x (T - 298)

To determine the quantum numbers of the last electron in the magnesium ion (Mg2+), we need to first determine the electronic configuration of the ion.

The question is incomplete but I have to look at the electron configuration of the magnesium ion.

Magnesium (Mg) has an electronic configuration of 1s2 2s2 2p6 3s2, which means it has two electrons in the 3s orbital. When magnesium loses two electrons to form the Mg2+ ion, these electrons are removed from the 3s orbital, leaving a filled 1s orbital, filled 2s orbital, filled 2p orbital, and empty 3s orbital.

The quantum numbers of the last electron in the Mg2+ ion can be determined as follows:

Principal quantum number (n): The last electron is in the 2p orbital, so its principal quantum number is n=1.

Azimuthal quantum number (l): The azimuthal quantum number specifies the shape of the orbital and is given by the formula l = n-1. Therefore, the last electron has an azimuthal quantum number of l=1

Magnetic quantum number (m): The magnetic quantum number specifies the orientation of the orbital in space and can take integer values from -l to +l. Therefore, the last electron in the Mg2+ ion has a magnetic quantum number of m=-1, 0 or 1, since there is only one electron in the 2p orbital and it is spherically symmetric.
