AI Thread Summary
Eighth graders can produce hydrogen fuel from water using an electrolytic cell. The process involves separating hydrogen from H2O by applying a direct current to water mixed with a small amount of sulfuric acid to enhance conductivity. At the negative electrode (cathode), hydrogen gas (H2) is generated, while oxygen gas (O2) is produced at the positive electrode (anode). This method effectively demonstrates the principles of electrolysis. Understanding this process can help students grasp fundamental concepts in chemistry and renewable energy.

I was given a task for homework. I am in 8th grade and please could you tell me how you separate hydrogen from h2o and make hydrogen fuel. thanks

with a electrolytic cell containing water and a little sulfuric acid (for a good conduction) a anode and kathode and dc current from an outside voltage source. At the negative side you will obtain H2 at the positive side O2.

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...
