AI Thread Summary

In the reaction 2C2H2 + 5O2 -> 4CO2 + 2H2O, the oxidation state of oxygen in the reactants is 0, while in the products, it is -2. The carbon in acetylene (C2H2) is oxidized from an oxidation state of -1 to +4 in carbon dioxide (CO2). The confusion arises regarding the reduction products, as oxygen is incorporated into the products CO2 and H2O. Overall, the reaction involves the oxidation of carbon and the reduction of oxygen, with oxygen's oxidation state changing from 0 to -2. Understanding these changes is crucial for grasping the redox nature of the reaction.

Oxidation: 2C₂^- -> 4C⁴⁺ + 12e^-

I am confused to where the reduction products are becuse the oxygens are part of the carbon dioxide and the water. Could somone please help me?

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...
