AI Thread Summary

The formula for ATP is C10H16N5O13P3, which contains five nitrogen atoms. To calculate the weight percentage of nitrogen in 0.16 mol of ATP, one must first determine the molar mass of ATP and the total mass contributed by nitrogen. The confusion regarding the amount of nitrogen in 0.16 mol is clarified by noting that the weight percentage calculation does not depend on the quantity of the substance. Instead, it is based solely on the composition of the compound. Therefore, the weight percentage of nitrogen remains constant regardless of the amount of ATP measured.

C10H16N5O13P3 is the formula of ATP. What is the weight precentage of Nitrogen in 0.16 mol of ATP?

Does it mean that in 0.16 mol of ATP I have 0.16 mol of N? or maybe of N5? I'm confused...

0.16 mol is there just to confuse you. Weight percentage on element in a substance doesn't depend on the substance amount.

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...
