AI Thread Summary
The discussion revolves around a request for assistance with stoichiometry problems related to a fence and rail method, specifically problems #8 and #9. The user expresses uncertainty about the method, indicating it may have been covered earlier in their textbook. They seek help in setting up mass-to-mass conversions for these problems. The focus remains on understanding stoichiometry rather than the specifics of the fence and rail method. Overall, the user is looking for guidance to solve these chemistry problems effectively.

I honestly don't remember the teacher teaching this but I need help with.

I attached image of #8, and #9Only those 2^

No idea what the fence and rail method is, but I suppose it was explained earlier in the book. Other than that, these are simple stoichiometry problems.
 
Would you help me set up mass to mass?

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...
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...
