AI Thread Summary
The discussion centers on calculating the percentage yield of impure benzoic acid synthesized from benzyl alcohol. The theoretical yield is 5.93g, while the experimental yield is 6.13g, leading to a calculated percentage yield of 103.4%. This result raises questions about the validity of exceeding 100% yield, which is possible due to impurities in the product. It is emphasized that for crude materials, yields can surpass 100%, and it is essential to rationalize the presence of impurities in the analysis. Additionally, the discussion suggests proposing methods for the removal of these impurities in the final report.

i'v synthesized benzoic acid from benzyl alcohol and i have a theoretical value for the yield and and experimental yield of impure acid.

Theoretical Yield = 5.93g
Impure Yield from experiment = 6.13g

Now, my paper asks for the percentage yield of my impure acid, how does that work?

If i do:
6.13/5.93 x 100 then I am going to get a percentage yield of 103.4%

Is that right? surely i can get a yield greater than 100% ?

Later in the experiment it asks for the yield of pure acid which i have done with a reasonable %, i just don't understand it for the impure acid.

Your yield for a crude material can be anything... even >100%. You must explain (rationalize) the impurity in your discussion and suggest a method for its removal.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
