    Fuel Hydrogen
AI Thread Summary
Hydrogen can be produced from various materials, including oil, coal, and biomass. While spacecraft utilize liquid hydrogen stored at low temperatures, this method is impractical for domestic use due to high costs and refrigeration requirements. The discussion highlights the need for alternative storage solutions for hydrogen to make it viable for homes and vehicles. There is also a call for exploring other hydrogen-bearing compounds that could facilitate easier storage and transportation without the need for cryogenic conditions. Overall, addressing these challenges is crucial for hydrogen to become a sustainable energy source for the future.

I have several questions about hydrogen that I need help to answer them.

gasoline; raw oil; mineral coal; wooden coal; dry biomass
Which of the following materials could be use to produce hydrogen?
I think they are the oil and the coals. Maybe biomass.

Spaceships utilize hydrogen as fuel. It is stored in liquid state at low temperature and high pressure. This storage method is not adequate for domestical uses nor for utilization in transports. How could we store hydrogen to apply as a fuel in our homes and cars?

And what are the problems to surpass in order to make hydrogen the fount of energy of the future?

Thank you :biggrin: .

Any material containing hydrogen could be used to produce hydrogen. What on your list contains hydrogen?

Spacecraft use hydrogen which is stored as a liquid, which requires a cyrogenic storage (i.e. very cold), which does not necessarily mean high pressure. Cryogenic storage would not seem practical for household applications because of the cost of such storage and the fact that a refrigeration may be required to maintain the necessary temperatures if the hydrogen is not used for some period of time.

We already have methane or natural gas powered vehicles. Can one think of other hydrogen-bearing compounds which would provide practical storage and transportation options without the need for cryogenic temperatures?
 
Thank you very much, Astronuc.
 
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...
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...
