Explanation:
The given data is as follows.
Pressure (P) = 170 torr, mass of heptane (m) = 86.7 g
First, we will calculate the number of moles as follows.
No. of moles = 
= 
= 0.867 mol
Now, the number of moles of 
are calculated as follows.
No. of moles =
= 
= 1.07
Therefore, mole fraction of heptane will be calculated as follows.
Mole fraction = 
= 
= 
= 0.445
Now, we will calculate the partial pressure of heptane as follows.
= 
= 75.65 torr
Thus, we can conclude that the partial pressure of heptane vapor above this solution is 75.65 torr.
Answer:
Nuclear transmutation
Explanation:
The process in which an element spontaneously transforms into another isotope of the same element, or into a different element is called nuclear transumutation. It occurs when the number of protons or neutrons in the nucleus of an atom is changed.
P2 = 40 atm
Explanation:
Given:
P1 = 2 atm
V1 = 1200 L
V2 = 60 L
P2 = ?
Using Boyle's law and solving for P2,
P1V1 = P2V2
P2 = (V1/V2)P1
= (1200 L/60 L)(2 atm)
= 40 atm
Answer:
Explanation:
In this case, for the dissociation of hypochlorous acid, we know that the acid dissociation constant (Ka) is 2.9x10⁻⁸, which is related with the Gibbs free energy as shown below:
But in this case K is just Ka, therefore, at 296 K, it turns out:
Such result, means that the reaction is nonspontaneous at the given temperature, it means it is not favorable (not easily occurring).
Best regards.
