Answer:
<h2>The answer is 23.63 mL</h2>
Explanation:
In order to find the new volume we use the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
From the question
P1 = 6.3 atm
V1 = 9 mL
P2 = 2.4 atm
So we have
We have the final answer as
<h3>23.63 mL</h3>

One definition of an acid is a molecule that can donate a H+ ion. So for example if you have an acid such as hydrochloric acid (HCl) in water, HCl will donate it's H+ to the H2O molecule, forming Cl- and H3O+.
In contrast, a base is a molecule that accepts H+ ions. This means a base such as NH3 reacts with H2O to form OH- and NH4.
So when pH is measured, it is the ratio of H3O+ ions to OH- ions. If there are more H3O+ ions, you then know that there are more acidic molecules in the solution, since they must be giving away their H+ ions.
So a solution with an acid in it will have more H3O+ ions (which can be described as H+ ions) in it. However, an acid by itself will have nothing to donate H+ ions to.

No, the biosphere does not exhibit a clear boundary as life always comes to an end.
The biosphere comprises all the living things of the world, like all the plants and animals. It is considered as the global ecosystem, that is, the gathering of all the planet's ecosystems. It comprises the land and the atmosphere. It is usually considered as the zone of life, where all the species of the planet thrives.
Answer : The property in the wrong column is, base form hydrogen gas with metals
Explanation :
Acid : It is a substance that has ability of donating a proton or hydrogen ion, 
.
The properties of an acid are :
- Acids are sour in taste.
- It conduct electricity.
- The texture of an acid solution is sticky.
- It react with carbonates to give salt.
- It changes the color of the litmus paper to red.
- It react with a metal to give compound and hydrogen gas.
Base : It is a substance that has ability of donating hydroxide ion, 
.
The properties of an base are :
- Base are bitter in taste.
- It conduct electricity.
- The texture of an base solution is slippery.
- It changes the color of the litmus paper to blue.
- It does not react with a metal.
Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals
.
