The solution would be like
this for this specific problem:
<span>(78.6 kJ) / (92.0 g /
(46.0684 g C2H5OH/mol)) = 39.4 kJ/mol </span>
<span>39.3 </span>
So the approximate molar
heat of vaporization of ethanol in kJ/mol is 39.3.
I hope this answers your question.
Answer:
differential equation fora in terms of t is
Explanation:
Given :
Rate at which the reaction takes place is proportional to the square root of the amount of substance A present.
the amount of substance A present (measured in grams) at any time t = a
orbitary constant = k
Solution
The rate of change of the reaction is
Thus , if amount present is low then will be high
Now
Volume = v(t) = 25-(12-11)t
Volume v(t) = 25 –t
= 12 (200 grams) - 11/(v(t))a
converting 200 gram to kg we get
= 12 (0.2) - 11/(v(t))a
If people over mine in Georgia there could be too much pollution. Also, it could cause a lot of damages to natural resources.
