2. The number of molecules of product formed would be 3 moles.

In the diagram, the green ball is [tex]A_2[/tex] and the blue ball is [tex]B_2[/tex]. Both react to form [tex]AB_3[/tex] according to the following equation:

[tex]A_2 + 2B_3 --- > 2AB_3[/tex]

From the equation, the mole ratio of [tex]A_2[/tex] to [tex]B_3[/tex] is 1:2. There are 6 green balls ([tex]A_2[/tex]) and 3 blue balls ([tex]B_2[/tex]) in the image. In other words, the ratio of [tex]A_2[/tex] to [tex]B_3[/tex] in the image is 2:1.

Thus, [tex]B_2[/tex] is limiting in availability.

From the equation, the mole ratio of [tex]B_2[/tex] to [tex]AB_3[/tex] is 1:1. With 3 moles of  [tex]B_2[/tex]  limiting the reaction, only 3 moles of [tex]AB_3[/tex] will also be produced going by the mole ratio.

The unit cell edge length in pm is 361 pm.

given that :

the density of the metal , ρ = 8.96 g/cm³

atomic mass = 63.54 g/mol

the atomic cell = 4 atoms

Avogadro's number = 6.022 × 10²³ atoms/mol

the expression is given as follows :

cell volume =  (atoms × atomic mass ) / density × Avogadro's number)

                    = ( 4 × 63.54 ) / 8.96 × 6.022 × 10²³)

                    = 4.71 × 10⁻²³ cm³

Anything that moves in a net direction from a region of higher concentration to a region of lower concentration is said to be diffusing. Because the particles in liquids and gases travel randomly from one location to another, diffusion occurs in these media.

Diffusion is the overall net movement of anything from a higher concentration to a lower concentration. A gradient in the Gibbs free energy or chemical potential drives diffusion.

The molecules' kinetic energy causes random motion, which causes diffusion. This mechanism happens in simple diffusion without the help of a transport protein. The molecules travel from an area of high concentration to an area of low concentration due to their random mobility.

One mole of a compound is a unit of measurement that represents 6.022 x 10^23 particles of a compound. This number is also referred to as Avogadro's number and is the ratio of particles to moles in a given compound.

What is Avogadro's number?
The proportionality factor that connects the number of constituent particles (typically molecules, atoms, or ions) in a sample with amount of substance in that sample is called the Avogadro constant, also known as NA or L. It has an exact value of 6.022140761023 reciprocal moles and serves as a SI defining constant. Stanislao Cannizzaro named it after the Italian scientist Amedeo Avogadro, who explained this number at the Karlsruhe Congress in 1860, four years after Avogadro's passing. The Avogadro number is a dimensionless number that represents the Avogadro constant as a numerical value expressed in reciprocal moles. The Avogadro number, or Nor N0 in older literature, is the exact number of particles (6.022140761023) that make up one mole.

One mole of a compound is a unit of measurement that represents 6.022 x 10^23 particles of a compound.

In case of nh3, (N-H bonds makes between molecules) and dipole dipole interaction (interaction between two dipole) and london dispersion forces occur between nh3 molecules. this types of intermolecular forces are generated between nh3 molecules.

Considering the definition of empirical and molecular formula, the empirical formula is C₃H₅O₂ and the molecular formula is C₆H₁₀O₄.

The empirical formula or minimal formula is one that indicates the type of atoms that make up a compound, the minimum ratio of the integer number of atoms and not necessarily the exact number of atoms in it.

The molecular formula is the actual formula of the molecule and indicates the types of atoms and the number of each type involved in the formation of the molecule.

This formula can be obtained from the empirical or minimal formula, as long as the molecular mass of the compound is known. That is, divide the estimated molecular mass divided by the molecular mass of the empirical form. With the multiple obtained, we proceed to multiply the subscripts of the empirical formula, thus obtaining the molecular formula of the compound.

In this case, you know:

Assuming a 100 grams sample, the percentages match the grams in the sample. So you have:

Then it is possible to calculate the number of moles of each atom in the molecule, taking into account the corresponding molar mass:

The empirical formula must be expressed using whole number relationships, for this the numbers of moles are divided by the smallest result of those obtained. In this case:

The empirical formula must be expressed using whole number relationships, so:

Therefore the C: H: O mole ratio is 3: 5: 2

Finally, the empirical formula is C₃H₅O₂.

The molar mass of adipic acid is 146.1 g/mol and the molar mass of empirical formula is 69 g/mole.

Dividing the estimated molecular mass divided by the molecular mass of the empirical form, you get:

146.1 g/mol÷ 69 g/mol ≅ 2

This means that in the molecular formula there are 2 unit formulas, so it is necessary to multiply the number of all atoms by 2:

Molecular formula= 2×C₃H₅O₂

Molecular formula= C₆H₁₀O₄

The molecular formula is C₆H₁₀O₄.

As the temperature rises, so does the water vapor saturation pressure. The rate at which vapour pressure rises for each degree that the temperature rises is determined by the Clausius-Clapeyron equation. Specify p as the saturation vapour pressure and T as the temperature.

In honor of Rudolf Clausius and Benoît Paul Émile Clapeyron, the Clausius Clapeyron equation is a way of explaining a discontinuous phase transformation between two phases of matter of a single constituent. There is no direct relationship between a liquid's temperature and vapour pressure.

In P = RT/ΔHvap + C

Given,

P = 363 torr,

R = 8.314

T = 46.3°C

Forces that act in the same direction are additive in nature while opposing forces are subtractive.

As indigo makes hydrogen with itself making it non-polar, it remains insoluble in water whereas due to the basic property of leucoindigo, it acts as a polar compound becoming soluble in water.

With itself, indigo forms hydrogen bonds. The molecule is unable to form a connection with water as a result. Additionally, the molecule is quite symmetrical and has polar bonds with oppositely oriented dipole moments that cancel each other out, making it non-polar and insoluble in water. While water cannot dissolve apolar molecules, it may dissolve polar ones. In this manner, the leuco base of indigo is formed, resulting in a polar molecule that may dissolve in water. This leuco base is polar since it is a sodium salt.

What do you mean by polar and non-polar compounds?

Polar compounds are compounds that have slight charges (slightly positive and slightly negative) within the compound. The slight charges are due to electronegativity differences of .3 to 1.4.  Nonpolar compounds are compounds that do not have slightly negative and positive charges within the compound.
