Answer:
it looks good to me just pay attention to the subscriped, i always have trouble with that.
Explanation:
For this question, we apply the Raoult's Law. The formula is written below:
P = P*x
where
P is the partial pressure
P* is the vapor pressure of the pure solvent
x is the mole fraction
The partial pressure is solved as follows:
P = Total P*x = (250 torr)(0.857) = 214.25 torr
Hence,
214.25 = (361 torr)(x)
<em>x = 0.593 or 59.3%</em>
Anaerobic transformations of 1,1,1-trichloroethane (TCA), 1,1-dichloroethane (DCA), and chloroethane (CA) were studied with sludge from a lab-scale, municipal wastewater sludge digester. TCA was biologically transformed to DCA and CA and further to ethane by reductive dechlorination. TCA was also converted to acetic acid and 1,1-dichloroethene (11DCE) by cell-free extract. 11DCE was further biologically converted to ethene. This pathway was confirmed by transformation tests of TCA, DCA and CA, by tests with cell-free extract, and by chloride release during TCA degradation.
