Answer:
They all vibrate, but they all move differently.
Explanation:
Similarities: They all consist of particles and vibrate, just at different frequencies.
Differences: The particles in solids move slowly and vibrate. In liquids, they move a bit quicker and slide past one another. They will also take the shape of the container they're in. In gases, they move freely at high speeds and also taking the shape of the container.
Hope this helped! :)
Answer : The volume of the balloon at the new location is, 591.3 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.995 atm
= final pressure of gas = 0.720 atm
= initial volume of gas = 500 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Therefore, the volume of the balloon at the new location is, 591.3 L
Answer is: molar mass of xylene 106,18 g/mol.
m(xylene) = 7,94 g.
m(cyclohexane) = 132,5 g.
T (solution) = - 4,9 °C.
Tf(cyclohexane) = 6,5 °C, frezing point.
Kf(cyclohexane) = 20,2 K·kg/mol; cryoscopic constant.
ΔT(solution) = 6,5°C - (-4,9°C) = 11,4°C = 11,4 K.
M(xylene) = Kf · m(xylene) ÷ m(cyclohexane) · ΔT(solution).
M(xylene) = 20,2 K·kg/mol · 7,94 g ÷ 0,1325 kg · 11,4 K.
M(xylene) = 106,18 g/mol.

Answer:
warming up the solution.
Explanation:
- A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
- Supersaturated solution is a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.
- A saturated solution can become supersaturated when it is cooled.
- Also, we can form a saturated solution from a supersaturated solution via warming up the solution:
<em>The solubility of solid solutes in liquid solvents increases as the solvent is warmed up.</em>
