Dipoles are not the dominant intermolecular forces between IBr molecules in liquids. IBr is a covalent bond.

A covalent bond is a chemical bond that requires the sharing of electrons to form electron pairs between atoms. The constant balance between attractive and repulsive forces between atoms according to their share of electrons is called a covalent bond.

Covalent bonds are much more common in natural chemistry than ionic bonds. A covalent bond is the simultaneous attraction of the nucleus to one or more electron pairs. Covalent compounds generally have low boiling and melting factors and are determined in all three body states at room temperature. Covalent bonds no longer conduct electricity; This is because covalent compounds no longer have charged particles that can carry electrons.

The root mean square speed of O₂ gas molecules under the same conditions is 521.04ms⁻²

Kinetic energy is the energy an object has because of its motion

Here given data is

He gas = 6950 j/mol

We have to find root mean square = ?

So the formula is to find root mean square is

Vrms = √RT/m

Vrms = RMS velocity of the gas

T = absolute temprature of the gas

M = molar mass of the gas

R = universal gas constant

So, average molar kinetic energy of gas

E = 1/2 mv²rms = 1/2 RT

This equation reveal that molar KE is independent of the nature of the gas and it only depends on temprature as ideal behavior is concerned and so both He and O₂ will have same KE = 6950 j/mol and under the same condition of temprature

So for O₂

1/2 m O₂ V²rmsO₂ = 6950 j/mol

Taking atomic mass of O₂ = 16g/mol

V²rmsO₂ = 6950 × 2/2×16g/mol

VrmsO₂ = √69500000/16g/mol

VrmsO₂ = 521.04ms⁻²

As a result, we will obtain a number closer to 1.49. Thus, the original solution's polarity is as follows.

The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. Molarity is defined as the number of moles of solute per liter of solution.

The moles of solute per liter of solution is measured as molarity. For instance, when table salt is dissolved in water, water serves as both the solution and the solute. Sodium chloride weights 58.44 grams per mole. One liter of water and 58.44 grams of sodium chloride combine to form one molar solution, or 1M.

100 g of a solution Additionally, it is assumed that the starting density is 1.02 grandpa. We can therefore determine the volume or solution from this information. Volume of the solution is therefore equal to the solution's mass divided by its city. So we have 100 g of solutions here. Therefore, 100 g make up the majority of the solution. Divided by the solution's density, 1.02 grandpa is obtained. The result will be 98.04 cm. The volume motor solution is now available. Next, we may determine the initial solution's polarity.

Magnesium carbonate (MgCO3) is basic in nature and insoluble in water but when 0.1m HNO3 (acidic) is added the MgCO3 will dissociate due to the opposite nature that is MgCO3 is basic and HNO3 is acidic. This will lead to an increase in solubility. The balanced equation of this reaction is:

MgCO 3 (s) + 2 HNO 3 (aq) → Mg(NO 3) 2 (aq) + CO 2 (g) + H 2O (l)

The equilibrium constant for the dissolution of a solid substance into an aqueous solution is the solubility product constant. Ksp is used to represent it.

A type of equilibrium constant, the solubility product's value changes with temperature. Due to increasing solubility, Ksp often rises as temperature rises.
