Considering the definition of molality, the molality of the KCl in the solution is 6.56 moles/kg.

Molality, or molal concentration, is the amount of a substance dissolved in a given mass of solvent. It is defined as the moles of a solute per kilogram of solvent.

The Molality of a solution is determined by the expression:

molality= number of moles of solute÷ kilograms of solvent

Molality in this case

In this case, you know:

mass of KCl= 105 g

mass molar of KCl= 74.55 g/mole

number of moles of solute= mass of KCl÷ mass molar of KCl= 105 g÷ 74.55 g/mole= 1.41 moles

Mass of solvent = 215 g of water= 0.215 kg (being 1000 g=1 kg)  

Replacing in the definition of molality:

Molality= 1.41 moles÷ 0.215 kg

Molality= 6.56 moles/kg

The molality of the solution is 6.56 moles/kg.

Once an action potential reaches the end bulbs of a neuron, the first event in synaptic transmission is the release of neurotransmitters from the presynaptic neuron.

When an action potential reaches the end bulbs, it causes the opening of voltage-gated calcium channels in the presynaptic membrane. This influx of calcium ions into the presynaptic neuron triggers the release of neurotransmitters stored in vesicles at the synapse.

The neurotransmitters then diffuse across the synaptic cleft, the small space between the presynaptic and postsynaptic neurons, and bind to receptors on the postsynaptic membrane. This binding causes a change in the electrical or chemical properties of the postsynaptic neuron, leading to the initiation or inhibition of an action potential in the postsynaptic neuron.

It's worth noting that, this process is called synaptic transmission, it's the process by which an action potential in one neuron causes an electrical or chemical signal in another neuron, muscle cell or gland cell.

Answer: The correct answer is Option A. Compound Y will have the highest boiling point.

Intermolecular forces are the forces that hold the molecules of compounds together. The more the strength of these forces is more will be the force of attraction between them. Hence a compound having stronger intermolecular forces will be hard to break or boil.

So a compound having strong intermolecular force will have a high boiling point as it takes more energy to break apart these molecules.

In the given question compound Y has highest boiling point so it has the maximum intermolecular force between its atoms or molecules.

To determine the [OH-] of a solution, we can use the relationship between the acid dissociation constant (Ka) and the base dissociation constant (Kb).

The relationship is: Kb x Ka = Kw

Where Kw is the ion product constant of water which is 1.0 x 10^-14 at 25°C.

We know that the Ka of HF is 6.8 x 10^-4. To find the Kb of F-, we'll use the above terms.

Kb x 6.8 x 10^-4 = 1.0 x 10^-14

Kb = 1.0 x 10^-14 / 6.8 x 10^-4

Kb = 1.47 x 10^-11

To find the [OH-] of the solution, we'll use theformulae:

The molar mass of the unknown gas is 17.64 g/mol.

Molar mass is a measure of the mass of a given chemical compound, which is calculated by dividing the mass of the substance in grams by its amount in moles.

The molar mass of the unknown gas can be calculated using Graham's law of effusion, which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. The equation can be written as follows:
rate of effusion of unknown gas = (rate of effusion of methane) x (sqrt(molar mass of unknown gas))/sqrt(molar mass of methane)
Substituting the given values, we get:
29.0 ml/min = (47.8 ml/min) x (sqrt(molar mass of unknown gas))/sqrt(16.04 g/mol)
Solving for the molar mass of the unknown gas, we get:
