According to the Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.

What is Gay-Lussac's law?

Gay-Lussac's law is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.

The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .The law is given by the formula, V₁/T₁=V₂/T₂, which on substitution gives T₂=95×100/300=31.6 °C.The container in Gay-Lussac's law is considered to be rigid  in contrast to the container present in Charle's law.

Thus, as per  Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.

Calculate the volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr.

14L
128 L
0.007 L

Answers

The volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr is 128.01L.

How to calculate volume?

The volume of a gas can be calculated using ideal gas law equation as follows:

PV = nRT

Where;

P = pressureV = volumen = number of molesR = gas law constantT = temperature

P = 705torr = 0.93atmV = ?T = 145Kn = 10R = 0.0821 Latm/molK

0.93 × V = 10 × 0.0821 × 145

0.93V = 119.05

V = 128.01L

Therefore, the volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr is 128.01L.

What does it mean that the collisions between gas particles are elastic?

Answers

Answer:

There is no net loss of energy from the collisions.

Explanation:

Gas particles are constantly colliding with each other and the walls of their container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container.

It means that there is no net loss of energy from the collisions. An elastic collision is one in which there is no overall loss of kinetic energy.

Which of the following diagrams shows how osmosis would affect a plant cell when placed in a solution with a lower solute concentration than its own?


A.
Diagram Y
B.
Osmosis is not dependent on solute concentration.
C.
Diagram Z
D.
Diagram X

Answers

Answer:

Diagram Z

Explanation:

A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Answer:

Diagram Y

Explanation:

Osmosis is the passive movement of water molecules across (into or out of) a cell membrane. "Passive" means that the process occurs automatically without the need for chemical energy.

In the diagrams above, a plant cell is shown as it would appear in a solution with a solute concentration more than its own (X), a solution with a solute concentration equal to its own (Y), and a solution with a solute concentration less than it own (Z). The movement of water is toward the area of more solute concentration (and therefore less water concentration).

The answer, then, is Diagram Y.

A high pressure area is an area where the air sinks. As it does, it warms up by the adiabatic effect of a greater pressure and that causes the clouds to evaporate, giving place to a clear sky

Explanation:

A high-stress area, high, or anticyclone, is a location in which the atmospheric stress on the surface of the planet is more than its surrounding environment.

What are the traits of the high-pressure system?

In a high-Pressure system, it has better pressure in its center than in the regions around it. Winds blow away from excessive pressure.

Swirling withinside the contrary route from a low-stress system, the winds of an excessive pressure system rotates clockwise north of the equator and counterclockwise south of the equator.

Answers

Answer:

The balanced equation is: H2 (g) +Cl2 (g) →2HCl (g)

Explanation:

Balancing chemical equation refers to balancing the stoichiometric coefficients on the reactants and products side. This must be done as the chemical equation obeys the law of conservation of mass and momentum.

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. The Law of conservation of mass governs the balancing of a chemical equation.

Given chemical equation

The balanced chemical equation for the hydrogen + chlorine -> Hydrogen Chloride.

H2 + Cl2 → 2HCl

The equation is balanced as on the reactants side there are two hydrogens present and the same on the products side. For chlorine as well the same thing goes two chlorine atoms on the reactants side and two on the products side.
