AI Thread Summary
Water and chloroform form separate layers due to their differing polarities, despite both being polar molecules. Water is highly polar and forms strong hydrogen bonds, while chloroform, though polar, has a significantly lower polarity. This difference in polarity prevents them from mixing, leading to distinct layers. To quickly identify which layer is water and which is chloroform, one can use the density method; water is denser than chloroform, so the lower layer will be water. The distinct smells of chloroform further indicate its presence in the upper layer.

Q: When water and chloroform, CHCl3, are mixed, the two components separate into two distinct layers, each of which smells strongly of chloroform. Account for these observations in terms fo the polarity of the two substances involved. Describe how you could very quickly determine which of the two layers is mainly water and which is mainly chloroform.

H2O is a polar molecule. CHCl3 is also a polar molecule. Given that "like dissolves like" they should turn into one solution.

There is a huge difference between their polarities. And they are completely different - water 'loves' ions and molecules able of creating hydrogen bonds.

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...
