We are given the series of chemical reactions:
Ethane is chlorinated in a continuous reactor:
C2H6 + Cl2 --> C2H5Cl + HCl
But some of the product monochloroethane becomes further
chlorinated by an undesired side reaction:
C2H5Cl + Cl2 --> C2H4Cl2 + HCl
So to avoid the product monochloroethane to be further
chlorinated, there must be fast processing or fast conversion of ethane so that
there would less time for further chlorination. Hence we must design the
reactor for high conversion of ethane.
To make the process economical, there must be a
downstream separation step that would separate the main product monochloroethane
from the undesired product dichloroethane.
Answer: Redundancy
Explanation:
The data redundancy is one of the type of condition in the database where we can easily store our data or information in more than two different places in the computer system memory. It is basically helps in correcting and also detecting the different types of errors in the stored data.
According to the given question, the school is basically keeping the two different list but the address and the name of the student information are similar and this is refers as data redundancy.
Therefore, Redundancy us the correct answer.
Answer: Other Engineers
Explanation:
Richard can be sued by motorist in the event of the collapse of the road which he supervised construction, and the case would be considered with the already established engineering standards. The engineer standard directs that during construction or fabrication in engineering, the engineer should give little or no allowance for failure, because failure can lead to serious injuries or loss of life.
Answer:
profit increase by 750 dollars
Explanation:
We must base our analisys considering only the loan board associated cost:
<em><u>contribution per long board:</u></em>
300 sales price - 225 variable cost = $75
total contribution for 250 units:
250x$75 = 18,750
<em><u>increase in fixed cost:</u></em>
69,000 - 51,000 = 18,000
incremental operating profit:
18,750 contribution - 18,000 fixed cost = 750
