Explanation:
The given data is as follows.
Flow of chlorine (Q) =
Amount of liter present per day is as follows.
It is given that dosage of chlorine will be as follows.
10 mg/l = kg/l
Therefore, total chlorine requirement is as follows.
Total chlorine requirement = kg/day
= 100 kg/day
Thus, we can conclude that the kilograms of chlorine used daily at the given water treatment plant is 100 kg/day.
Answer: 35.1 kJ/mol
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
(1)
(1)
The final reaction is:
(3)
By adding (1) and (2)
Hence the expected value for the heat of sublimation of acetic acid is 35.1 kJ/mol
