Answer:
75.0%
Explanation:
Data obtained from the question. This includes the following:
Actual yield = 6.13g
Theoretical yield = 8.17g
Percentage yield =...?
The percentage yield can be obtain by using the following formula:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 6.13/8.17 x 100
Percentage yield = 75.0%
Therefore, the percentage yield of water from the reaction above is 75.0%
Answer:
<h2>C) All of the hydrogen atoms of benzene are equivalent.</h2>
Explanation:
Benzene is an aromatic hydrocarbon made up of six carbon atoms and six hydrogen atoms. Each hydrogen atom of the benzene is equivalent to each other. Due to the delocalized electron, it shows resonance property and thus is more stable. Mostly benzene shows substitution reaction than in addition reaction. It shows planarity and follows Huckle's rule. It forms many important derivative aromatic compounds.
