Answer: Option (B) is the correct answer.

Explanation:

Cooling the solvent will not increase the rate at which a solute dissolves because when we cool the solvent then the movement of particles decrease.

Therefore, there will be less interaction between the solute and solvent particles as a result the rate of dissolution decreases.

Whereas on crushing the solute the number of solute particles increases. Hence, there will be more interaction between solute and solvent particles and the rate of dissolution increases.

Also, on stirring the solvent there will be more interaction between solute and solvent particles. As a result, the rate of dissolution increases.

Upon heating the solvent, the particles of both solute and solvent get excited which will result in more interaction through the collision. Therefore, the rate of dissolution will increase.

Answer:

(a) when both the liquid are mixed, they become completely miscible as the intermolecular forces between them are equal to the intra molecular forces

(b) since the magnitude of intermolecular force = intra molecular forces, Delta H solution=0

Delta H solvent = positive

Delta H mix = negative

Bacteria and viruses are inactivated by temperatures above 139 ∘C in an autoclave. An autoclave contains steam at 1.00 atm and 1

andrezito [222]

To answer this question, we will use pressure law which states that:
"At constant volume of a fixed mass of gas, the pressure of the gas is directly proportional to the temperature"

This means that:
Pi / Ti = Pf / Tf where:
Pi is the initial pressure = 1 atm
Ti is the initial temperature = 100 + 273 = 373 degree kelvin
Pf is the final pressure that we want to calculate
Tf is the final temperature = 139 + 273 = 412 degree kelvin

Substitute in the equation with the givens to calculate the pressure as follows:
1 / 373 = Pf / 412
Pf = (1/373) * 412 = 1.104557641 atm

FinnZ [79.3K]

In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.
