Balancing Redox equations half reaction method

AI Thread Summary
The discussion focuses on balancing the redox equation H2O2(aq) → H2O(l) in an acidic solution using the half-reaction method. The user expresses confusion about balancing ionic charges after addressing oxygen and hydrogen. The proposed solution includes the addition of electrons and protons, which is acceptable for a half-reaction. However, it is noted that if the task is to balance a full reaction, the current approach is inadequate. Clarification on whether to balance as a half or full reaction is essential for proper guidance.

Homework Statement


This is my equation. I needed to balance it in an acidic solution.

H2O2(aq)---->H2O(l)


Homework Equations


I know that you should balance oxygen using H2O & hydrogen using H+.
I am confused on how you balance the ionic charges.


The Attempt at a Solution


This is what I got for my answer
2 e- + 2H+ +H2O2---->2H2O

Not clear to me what you are doing - are you expected to balance a half reaction? If so, what you did is OK.

What you wrote suggests you are asked to balance it as a full reaction, which is impossible.

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...
