Answer:
ExplanatioHydrogen cannot exist in free state as hydrogen needs an electron to attain stability. If an element does not attain stability it cannot exist on its own. In Sun there are large number hydrogen atoms and helium atoms present this creates a lot of energy and nuclear fusions are occured. Gases that attain stability can normally exist on their own. E.g. Argon, Neon, Helium, Krypton and Xenon. Gases that cannot exist on their own are:
H2
O2
N2

Answer:
a) The volume increases
b) The volume decreases
c) The volume does not change
Explanation:
<em>A gas at a pressure of 2.0 atm is in a closed container. Indicate the changes (if any) in its volume when the pressure undergoes the following changes at constant temperature and constant amount of gas.</em>
<em />
When there is a change in the pressure (P) at constant temperature (T) and amount of gas (n), we can find the change in the volume (V) using Boyle's law.
P₁.V₁ = P₂.V₂
where,
1 refer to the initial state
2 refer to the final state
<em>a) The pressure drops to 0.40 atm.</em>
P₁.V₁ = P₂.V₂
(2.0 atm) . V₁ = (0.40 atm) . V₂
V₂ = 5 . V₁
The volume increases.
<em>b) The pressure increases to 6.0 atm.</em>
P₁.V₁ = P₂.V₂
(2.0 atm) . V₁ = (6.0 atm) . V₂
V₂ = 0.33 . V₁
The volume decreases.
<em>c) The pressure remains at 2.0 atm.</em>
P₁.V₁ = P₂.V₂
(2.0 atm) . V₁ = (2.0 atm) . V₂
V₂ = V₁
The volume does not change.
I think it has a negative reaction.
