Answer:
35 minutes
Explanation:
The flow rate of the stream is the rate of volume of water with respect to time. It expresses the volume of water flowing per unit time.
Flow rate =
From the given question,
average flow rate of the stream = 420 cubic meters per minute, and the required volume = 14700 cubic meters.
So that;
time =
=
= 35
time = 35 minutes
Therefore, with the given average flow rate, the steam will produce 14,700 cubic meters of water in 35 minutes.
Answer:
(1) Bromination, (2) E2 elimination and (3) epoxidation
Explanation:
- In the first step, -OH group in cyclopentanol is replaced by more facile leaving group Br by treating cyclopentanol with
- In the second step, E2 elimination in presence of strong base e.g. NaOEt/EtOH produce cyclopentene
- In the third step, treatment of cyclopentene with mCPBA produces 1,2-epoxycyclopentane
- Full reaction scheme has been shown below
