Chemistry Relationship between moles of O2 and Ch2 Units in a combustion reaction

AI Thread Summary
The relationship between moles of O2 and CH2 units in a combustion reaction is directly proportional; as the number of CH2 units increases, the required moles of O2 for complete combustion also increases. A mathematical equation can be derived to express this relationship, typically based on the stoichiometry of the combustion reaction. The discussion emphasizes the importance of formulating a clear equation to represent this relationship. Additionally, participants encourage exploring beyond just mathematical patterns to deepen understanding. A well-defined chemical equation will clarify the relationship further.

Homework Statement



I want to find a relationship between the number of moles of O2 used and the number of CH2 units in an alkane in a complete combustion reaction.

Homework Equations





The Attempt at a Solution



Right now I have come up with a math equation, given X units of CH2, to find the number of O2 moles. I used patterns to find the equation, is there any other relationship? The more units of CH2 you have, the more O2 you need to combust it right?

This is very very elementary but just give a chemical equation if you want help although you seem to say you have solved it.
 
It was a generic question, I'm only concerned that I am not thinking outside of the box by considering only the mathematical relationship.
 
Until you write down what your actual thoughts are, preferably in some sort of formula or calculation, we do not know what you mean.

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...
