Why does changing the volume of a container change the pressure of the gas in it?

Chemistry

Answer:

Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.

Explanation:

The volume of a container is the space within the container. This is the amount of void the gas can occupy.

When the volume of a container is changed, the space either increases or decreases.

  • An increase in volume creates more space within the container.
  • This spreads out the force over a larger area.

When the volume of the container is reduced,

  • the force is confined to much smaller space.

The frequency of collision is higher for tiny spaces.

But lower for a large volume.

Fusion is safer than fussion because....
Goryan [66]

Answer: B, a fusion recrion creates waste material that is easier to store than fission.

Fusion produces far less harmful waste than fission does. The reliance of something independent like whether a reaction will stop on its own when something goes wrong is never indefinite (technological failures are unpredictable and destructive a lot of the time when it comes down to nuclear power).

N the reaction Mg + 2HCl -> MgCl2 + H2 which element’s oxidation number does not change?
BartSMP [9]

Answer:- Oxidation number of Cl does not change as it is -1 on both sides.

Explanations:- oxidation number of Mg on reactant side is 0 as it is in its elemental form(not combined with another element).

Oxidation number  of hydrogen in its compounds is +1, so if H is +1 in HCl the oxidation number of Cl is -1 as the sum has to be zero.

On product side, Mg oxidation number is +2 as the oxidation number of alkaline earth metals in their compounds is +2.

Two Cl are present in magnesium chloride, so if Mg is +2 then Cl is -1.

Oxidation number of H on product side is 0 as it is present in its elemental for, H_2 ,

So, it is only chlorine(Cl) whose oxidation number does not change for the given equation.
