There are five molecules of the water of crystallization.
Mass of hydrated copper(II) sulfate CuSO4 · xH2O = 0.755 g
Mass of anhydrous copper(II) sulfate CuSO4 = 0.483 g
Molar mass of hydrated copper(II) sulfate CuSO4 · xH2O = (160 + 18x) g/mol
Molar mass of anhydrous copper(II) sulfate CuSO4 =160 g/mol
Number of moles of hydrated copper(II) sulfate CuSO4 · xH2O = Number of moles of anhydrous copper(II) sulfate CuSO4
Therefore;
0.755 g/(160 + 18x) g/mol = 0.483 g/160 g/mol
0.755 * 160 = 0.483 (160 + 18x)
120.8 = 77.28 * 8.694x
120.8 - 77.28 = 8.694x
x = (120.8 - 77.28)/8.694
x = 5
The formula of the hydrated salt is CuSO4 · 5H2O.

which statement correctly explains why h2s is a stronger acid than water
Answer:
Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, weaker base than H2O.
Sulfur (S) has a larger atomic size than oxygen (O), so H, 2, S, , is a more stable, weaker base than H, 2, O.
Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, stronger acid than H2O.
Sulfur (S) has a larger atomic size than oxygen (O), so H, 2, S, , is a more stable, stronger acid than H, 2, O.
Sulfur (S) has a larger atomic size than oxygen (O), so HS– is a more stable, weaker base than OH–.
Sulfur (S) has a larger atomic size than oxygen (O), so HS, – , is a more stable, weaker base than OH, –, .
Sulfur (S) has a larger atomic size than oxygen (O), so HS– is a more stable, stronger acid than OH–.
I think the answer is the third one
It easily dissociates into ions in solution, releasing more hydrogen ions (H+). Therefore option A is correct.
[tex]\rm H_2S[/tex] (hydrogen sulfide) is a stronger acid than water because it readily undergoes dissociation in water to release hydrogen ions (H+).
This dissociation increases the concentration of H+ ions in the solution, leading to a lower pH value and stronger acidity. In contrast, water ([tex]\rm H_2O[/tex]) dissociates only to a small extent, resulting in a relatively lower concentration of H+ ions.
Therefore, [tex]\rm H_2S[/tex]'s ability to release more H+ ions makes it a stronger acid compared to water.
Therefore option A is correct.

when attempting to control someone or something, do people compromise their own freedom in the process?
Perception differs for a lot of people. I believe that attempting to control someone or something, will not make one compromise their own freedom in the process.
Why attempt to control someone if you are going to loose your right to do whatever you want or be free. One's aim to control is to be able to do what you want.Freedom is the right of an individual to be free and even though it can be compromised by the evil intensions of other people, it is not right to so it to yourself. Lossing your freedom over something is not worth it. Though some people do compromise their freedom for anything but not in all situations.So therefore, I believe that people do not compromise their freedom at all and Lost of freedom is not what a person desires.
