Answer:
The state of matter of a frozen fruit bar is solid. One property of solids is that they have a fixed shape, because the particles are tightly compressed and cannot move about. Another property is that solids can’t be compressed, because the particles have no space to move as a result of the compression. The frozen fruit bar has no free electrons so, like most other solids, it cannot conduct electricity.
Explanation:
Answer:
Vapour pressure of a liquid varies with temperature
Explanation:
The vapour pressure of any liquid is directly proportional to the temperature of the liquid. This implies that, as the temperature of the liquid increases, the vapour pressure increases likewise and vice versa.
Since the vapour pressure of liquid varies with the temperature of the liquid, it is essential to know the water temperature in the experiment to determine the vapour pressure of water.
Answer: 700 torr torr
Explanation:
Since the volume is constant
We use
P1/T1 = P2/V2
P1= 565torr torr, T1= 273+3= 276K, T2= 273+69= 342K
565/276 = P2/342
Simplify
P2= (565×342)/276 = 700.1 torr torr
Answer is: partial pressure of Xe is 22,95 atm.
m(He) = 10,5 g.
n(He) = m(He) ÷ M(He).
n(He) = 10,5 g ÷ 4 g/mol
n(He) = 2,625 mol.
m(Ne) = 10,5 g.
n(Ne) = m(Ne) ÷ M(Ne).
n(Ne) = 10,5 g ÷ 20,18 g/mol.
n(Ne) = 0,52 mol.
m(Xe) = 10,5 g.
n(Xe) = 10,5 g ÷ 131,3 g/mol.
n(Xe) = 0,08 mol.
Using <span>Dalton's law:
</span>p(Xe) = (0,08 mol / 0,08 mol + 0,52 mol + 2,625 mol) · 925 atm.
p(Xe) = 22,95 atm.
