In terms of molecular motion, why does an increase in pressure lead to an increased solubility of a gas?

Answers

Answer 1
Answer:  We imagine a piston cylinder and a solution of gas and water. Molecules are in constant random motion and some of the gas particles are in the vapor phase while some in the liquid phase. At a specific volume, molecules move freely. However, when the piston is moved down, increasing the pressure, some of the molecules in the vapor are pushed down to the liquid phase in order maintain equilibrium thus increasing solubility

As a consequence of the discovery of the nucleus by rutherford, which model of the atom is thought to be true? a. electrons are distributed around the nucleus and occupy almost all the volume of the atom.
b. protons, electrons and neutrons are evenly distributed throughout the volume of the atom.
c. the nucleus is made of electrons and protons

Answers

Electrons are distributed in shells revolving around the nucleus and occupy almost all the volume of the atom.

In the nucleus of an atom, proton and neutron are present whereas electrons are present in shells revolving around the nucleus. Most of the volume of an atom has empty spaces in which shells are present in which electrons are moving.

The number of protons and electrons are the same in an atom but the number of neutrons are different so we can conclude that electrons are distributed in shells that are present around the nucleus.

It should be noted that neutron and proton can be found in the nucleus of an atom. Also, there are electrons that are present in the shells that revolve around the nucleus.

In the atom, the number of electrons and protons are the same but there are different neutrons. Lastly, most of the volume of the atom has empty spaces.

Do x-rays travel slower than infrared

Answers

No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.

Which balloon is heavier, inflated or deflated

Answers

The deflated balloon has only the weight of the balloon skin, but the inflated one has the weight of the balloon skin and the air inside. This makes it heavier because air has a weight, even if it is very small it has a weight. If you filled it with helium, you might then think it was lighter but still a balloon filled with helium is still heavier than the deflated one because helium is less dense than air (since it rises) but still has a weight.
Hope this helped and if you need more help then just message me instead ok m:)     
The inflated balloon has more mass because the mass of the air inside of the balloon. The reason it floats is because the inflated balloon is less dense than the deflated one

Propanone is more soluble in water compared to 3 hexanol mainly because the propanone?

Answers

Propanone is more soluble in water compared to propane mainly because propanone cannot hydrogen bond with themselves but can hydrogen bond with water molecules. One of the slightly positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on the oxygen atom of propanone. In order for 3-hexanol to bond with water, the van der Waals forces must be broken and also the stronger hydrogen bonds of water molecules and it needs a great amount of energy.
