The best situation that describes the ethical dilemma related to food engineering is that Pesticides protect our crops, but some studies show that they cause consumers to gain weight.
Answer: Option D
<u>Explanation:</u>
Ethical dilemma is a generally known as a decision making problem which might have both positive and negative causes. In the above case, All other option such as A, B, C doesn’t seems to be having both positive and negative causes.
But option D gives us both a positive and negative causes of the pesticides that it protects but on the other hand also causes weight gain to the consumers. Hence option D can be concluded as the correct answer.
the Percentage yield for the reaction = 48.8%
What is Percentage yield ?
The % ratio of the theoretical yield to the actual yield is known as the percent yield. It is calculated as the theoretical yield multiplied by 100% divided by the experimental yield. The percent yield is 100% if the theoretical and actual yields are equal. Because the real yield is frequently lower than the theoretical value, percent yield is typically lower than 100%. This may be due to incomplete or conflicting reactions or sample loss during recovery. If the percent yield is more than 100%, more sample than expected was retrieved from the reaction.
4 P + 3 O2 = P4O6
moles P = 75.3 g / 30.9738 g/mol= 2.43
moles O2 required = 2.43 x 3 / 4=1.82
actual moles O2 = 38.7 g /32 g/mol=1.21 so O2 is the limiting reactant
theoretical moles P4O6 = 1.21 / 3=0.403
theoretical mass P4O6 = 0.403 mol x 219.895 g/mol=88.6 g
% yield = 43.3 x 100/ 88.6 = 48.8 %
the Percentage yield for the reaction = 48.8%
