The pressure the gas exert the walls of the container will decrease because the gas particles hit the wall of the container

Answers

Answer 1

Answer: The statement is false. The pressure of a gas do not decrease as the gas molecules hit the walls of the container. According to the Kinetic Molecular Theory, collisions of the gas molecules or with the walls of the container are perfectly elastic. This means that energy is not lost as the molecules collide with each other or with the walls of the container.

A solution of H2SO4(aq) with a molal concentration of 4.80 m has a density of 1.249 g/mL. What is the molar concentration of this solution?

Answers

Imagine we have mass of solvent 1kg (1000g)
According to that: $molality =n(solute) / m(solvent) =\ \textgreater \ 4.8m = 4.8mole / 1kg$
= 4.8 mole * 98 g/mole = 470g
$m(H2SO4) = n(H2SO4)*Mr(H2SO4) =\ \textgreater \$ $=\ \textgreater \ Molarity = 4.8 mole / 1.2 L = 4 M$ m(H2SO4) which is =470g

m(solution) = m(H2SO4) + m(solvent) = 470 + 1000 = 1470 g
d(solution) = m(solution) / V(solution) =>
=> 1.249 g/mL = 1470 g / V(solution) =>
$Molarity = n(solute) / V(solution) =\ \textgreater \$

Answer: 4.078 M

Which of the following leads to a lower rate of diffusion? A. Heated gas
B. Lower molar mass of particles
C. Higher velocity of particles
D. Reduced temperature

Answers

Reduced temperature leads to a lower rate of diffusion. Hence, Option (D) is the correct answer.

What is Diffusiion ?

Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration.

Diffusion is driven by a gradient in Gibbs free energy or chemical potential.

Therefore, Reduced temperature leads to a lower rate of diffusion. Hence, Option (D) is the correct answer.
