Answer:
The answer to your question is below
Explanation:
Data
Test tube 1 Test tube 2
Magnesium + Sulfuric acid Magnesium + Acetic acid
Mg + H₂SO₄ Mg + CH₃COOH
a) Test tube 1 will have a more vigorous reaction than test tube 2.
b) Sulfuric acid is a strong acid and Acetic acid is a weak acid.
c)
i.- Sulfuric acid because is a strong acid
ii.- Acetic acid because is a weak acid.
Taking into account the definition of dilution, moles of solute (option C) is the only thing about the solution that does NOT change.
<h3>Dilution</h3>
When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
<h3>Summary</h3>
In summary, moles of solute (option C) is the only thing about the solution that does NOT change.

Answer:
EVEN DOE IT TOO LATE, ITS B
Explanation:
Well. Yeah. Basically.
1 mole of any gas is 22.4 L.
Not really sure if that answers your question but that's what i know.
Anyway if we are talking about the size then usually gases are filled with empty space.
