Chemistry Lewis dot structures of complex molecules

AI Thread Summary
The discussion focuses on determining the Lewis dot structures for two complex molecules. The first structure shows a potential error with a single bond between carbon and oxygen, raising questions about the oxygen's charge due to having six electrons. The second structure features a nitrogen atom with four bonds, prompting inquiries about the resulting charge. Participants emphasize the importance of ensuring that the structures represent neutral species as required by the assignment. Clarification on bond types and charges is sought to correct the proposed structures.

I am not at all sure this is correct and the software that accepts answers for my school agrees with that assesment, any assistance will be greatly appreciated

Your first answer has a single bond between the carbon and the oxygen. That oxygen also has six other electrons around it. Would that result in the oxygen having a charge? You also show the enamine (with friends like that, who needs enamines?) nitrogen having four bonds to it. What would the charge be for that? Does your assignment want you to postulate neutral species? I'm betting it does.

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...
