AI Thread Summary

To find the mole fraction of a 1.222 M solution with a density of 1.3250 g/mL and a compound molar mass of 97.80 g/mol, first calculate the mass of the solution using its volume. The mass of the solute can be determined from the molarity and the molar mass. Then, the total mass of the solution is the sum of the mass of the solute and the mass of the solvent (water). Finally, the mole fraction is calculated by dividing the moles of solute by the total moles of solute and solvent. This approach provides a clear method to solve the problem.

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...
