Whats the use of Hydrogen?
-
cannot find the answer from testbook
but on wiki it says
Hydrogen is used in powering stars in Proton-Proton nuclear fusion
Is this rocket science or combined science? im not gonna write that..
-
y cant u write it as rocket fuel or for fission reaction?
its acceptable -
Cos, it is not in syllabus ...Originally posted by 0lala:y cant u write it as rocket fuel or for fission reaction?

Hydrogen is used in rocket science... and it's a well known fact.
Studied metal refining? Hydrogen is used for that. But exact use I forget liao.
Check the reactivitity series.
Edit: Combined Science got write, but not in detail.
If not, hydrogen is also used for powering cars. Think textbook got write also. -
hydrogen used in forming H2O?
forgive me, i am crapping..
-
Cannot forgive....
Because you are correct. But too advanced for a combined Science student. Me don't know either. -
car fuel lah, short and sweet, and easy to find evidence
-
FUSION, not fission...
hydrogen.. can also be used as alternative fuel for a lot of things instead of the usual fossil fuels...
in stars, hydrogen fuses to become helium and there is a lot of energy created from this nuclear reaction... which powers stars.. like our own sun..Originally posted by 0lala:y cant u write it as rocket fuel or for fission reaction?

erm that question itself is dumb.Originally posted by Agenda:cannot find the answer from testbook

its like asking whats the use of carbon or whats the use of life or whatever. its just too philosophical -
He just needs answers that can be found in the textbook. Nothing to philosophical. Just vomit out everything you know can le.Originally posted by hisoka:erm that question itself is dumb.

How Can Hydrogen Help?
got from somewhere.
The only way to eliminate the human contribution to both the greenhouse effect and urban pollution is to opt for a new clean energy based on renewable sources. Overt 150 years, the trend in energy use has been toward reducing carbon consumption and increased use of hydrogen. Each dominant fuel, from wood to coal to oil, and perhaps to natural gas– has contained more and more hydrogen and less and less carbon. Each successive fuel has been cleaner and more powerful.
This clean energy can be found by following the trend to its natural limit and use pure hydrogen, a fuel with zero carbon content.
Where And How Can We Use Hydrogen?
Hydrogen has many potential energy uses, including powering nonpolluting vehicles, heating homes and offices, and fueling aircraft. City buses, automobiles, mining equipment are some proposed mobile applications that have progressed to demonstration. Home generators and large electrical generating systems represent emerging stationary applications. Thus, hydrogen has many applications and advantages. However, widespread use will require new means to distribute hydrogen from the producer to the end user, fueling stations and many other new technologies, concepts and support facilities. -
Hydrogen is used in the hydrogenation of margarine to help harden it and give it consistency.

use of carbon is a great question!
due to its chemical structure, it can be either the hardest substance in diamonds, or slidy and used in lubricants...
now there is almost unlimited potential in another structure called buckyballs...
carbon fibre can also be used as a very light and strong material in lots of things which have been exploited in racing cars and other things requiring both strength and lightness

Uses
Hydrogen was formerly used for filling balloons, airships, and other lighter-than-air craft, a dangerous practice because of hydrogen's explosive flammability; there were disastrous fires, e.g., the immolation of the German airship Hindenburg at its mooring at Lakehurst, N.J., in 1937. Helium is preferable for use in lighter-than-air craft since it is not flammable. Hydrogen is used in the Haber process for the fixation of atmospheric nitrogen, in the production of methanol, and in hydrogenation of fats and oils. It is also important in low-temperature research. It can be liquefied under pressure and cooled; when the pressure is released, rapid evaporation takes place and some of the hydrogen solidifies. -

hydrogen can be reuse as natural gas fuel which act as reuse fuel in the future if i'm not wrong. given the earth will running out of fossil fuels, they are trying way to get hydrogen out of water n hope it can be done in the future.Originally posted by the Bear:FUSION, not fission...

It's not healthy for the body, but hey, it does answer the question...Originally posted by the Bear:making Trans Fat.. which isn't a good use of it actually -
yeah.. then, there are other things too.. like in cutting torches which do not need the intense heat of acetylene, you can use the oxy-hydrogen torch

thats what it can be used for or whats why its useful or somethign like that rather than whats the ue of carbon.Originally posted by the Bear:use of carbon is a great question!

anyway hydrogen is used in pretty much everything from bombs, balloons, polymers, fats, proteins, humans, animals, etc -
huh?
you can use carbon for everything... charcoal, pencils... just keep thinkingOriginally posted by hisoka:thats what it can be used for or whats why its useful or somethign like that rather than whats the ue of carbon.

nvm its a matter of english.Originally posted by the Bear:huh?

Carbon is hard to understand. The topic on chirality almost killed me as I can't visualize 3D structures.Originally posted by the Bear:use of carbon is a great question!

But the buckyball thing, it's fun. Still trying to understand though... -
So long as anything burns, carbon can be found.Originally posted by the Bear:huh?

There's also radioactive carbon to find out the age of something. -
Off topic.. asking about hydrogen, not carbon ...
Er... but the common name for carbon fibres, is composite material, right ? -
no.. it's pure carbon..
like i said, the structure of carbon molecules allow you to do amazing things with them, so you can have stuff like diamond which is hard, you can have graphite which is soft and slidy and used for lubricants, you can turn them into buckyballs for nano-tech...
and it's all carbonOriginally posted by gd4u:Off topic.. asking about hydrogen, not carbon ...
