First calculate the mole fraction of each substance:
Acetone: 2.88 mol ÷ (2.88 mol + 1.45 mol) = 0.665
Cyclohexane: 1.45 ÷ (2.88 mol + 1.45 mol) = 0.335
Raoult's Law: P(total) = P(acetone) · χ(acetone) + P(cyclohexane) · χ(cyclohexane).
P(total) = 229.5 torr · 0.665 + 97.6 torr · 0.335
P(total) = 185.3 torr
χ for acetone: 229.5 torr · 0.665 ÷ 185.3 torr = 0.823
χ for cyclohexane: 97.6 torr · 0.335 ÷ 185.3 torr = 0.177
Answer:
the process of returning a land area to the condition it was in before humans used the land
Explanation:
Reclamation refers to the process of returning a disturbed ecosystem to its original status prior to the disturbance. Often times, the disturbance regimes that change the conditions of the ecosystem are created by humans.
<em>Reclamation is unlike reforestation in that the latter involves the process of planting trees in order to reestablish forest lands, not necessarily return the land to its previous status.</em>
Reclamations are often done to return lands to the original flora and fauna status before the disturbance regime.
Answer:
Although scientists have been working hard to find a cure to this deadly disease, yet a sudden new like this will not be considered at first to be true. In order to make the public believe in this report, there should be authentic results from the trial experiments showing at least 90% of patient recovery. Also, there should be enough investigation done on the side effects of this medicine and the ingredients used in its making.
Answer:
The value of equilibrium constant is 29.45.
Explanation:
Moles of hydrogen gas = 2.00 mol
Concentration of hydrogen gas =
Moles of iodine gas = 1.00 mol
Concentration of iodine gas =
initially
2.00 M 1.00 M 1.00 M
At equilibrium:
(2.00-x/2) (1.00-x/2) x
Moles of HI at equilibrium = 1.80 M
Concentration of HI at equilibrium =
The expression of an equilibrium constant is given by ;
Putting x equal to 1.80 M.
The value of equilibrium constant is 29.45.
