A metal tank containing hydrogen gas has a pressure gauge that reads 575 psi. What is causing the pressure inside of the tank?

Answer: Yes, it is true, hydrogen bonding is strongest intermolecular forces compare with all. 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.

The goal of these washes is to neutralize an organic layer that might contain traces of acidic components. These washes are composed of saturated sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) in aqueous solutions.

Sodium bicarbonate is used to extract the mixture since doing so will cause any unreacted acid to react with the sodium bicarbonate and neutralize any remaining acid. When the acid had been neutralized, the water-soluble acid would separate from the water-insoluble ester. As a result, the yield of the pure product increases.

Explanation:

There are 2.716 moles are present in 500 gm of MgBr₂

The mass of a sample of a chemical compound is divided by the quantity of that substance, or the number of moles in the sample, measured in moles, to obtain the compound's molar mass in chemistry.

MgBr₂ is known as Magnesium bromide.

It is given that, Magnesium bromide of molar mass = 184.11 g/mol

As we know,

184.11 gm Magnesium bromide contains 1 mol

So, 500 gm Magnesium bromide contains 500 ÷ 184.11 = 2.716 mol

The approximate bond angles in ClBr₃ is 120 degrees.

Three connected nuclei in a molecule form an angle called a bond angle. Conventionally, the bond angle is thought to range from 0° to 180°.

In general, the number of lone pairs in an atom affects the bond angle. An atom with no lone pairs displays a trigonal planar shape, and in this instance the bond angle is 120°. A single lone pair in the molecule gives it a bent shape and a 118° bond angle.

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.
