AI Thread Summary

In the reaction 2Na + 2H2O → 2NaOH + H2, sodium (Na) is in the elemental state, giving it an oxidation state of 0. Hydrogen (H2) on the products side is also in its elemental form, thus maintaining an oxidation state of 0. Consequently, sodium undergoes oxidation as it loses electrons, while hydrogen is reduced as it gains electrons. The oxidation state of elements in their elemental form is always 0, confirming the oxidation and reduction processes in this reaction. This understanding is essential for analyzing redox reactions effectively.

I was given 2Na + 2H₂O → 2NaOH + H₂

My only question here is whether the Na on the reactants side is 0 because it is alone? And is it the same thing for the H₂ that is alone on the products side?

So if were the case Na would oxidize and H would reduce?

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...
