Whats the use of Hydrogen?

dun be stupidOriginally posted by gd4u:Cos, it is not in syllabus ...
as long as it correct,cambridge will give u the mark
its liek saying X=mk+c which is the same as X=c+km
but marker only give u marks for the 1st equation becauase the 2nd equation is not in the syllabus
well,not such thing
both is accepted regardless of how u phased it -
TO blow things up

0lala ... erm, like my (that) reply was supposed to be lame and sarcastic ... and supposed to be not useful to the TS qns ...
I am sorry to have caused u any distress for the misinterpretation (How come this line sounds so bloody familiar) -
yea,almost everything from this earth is carbon basedOriginally posted by the Bear: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 carbon

IT CAN MAKE WATER WHEN FUSED WITH OXYGEN!
GREEN VEHICLES!

Cannot hydrogen v flammable imagine a car full of huydrogen gt into an accident n KABOOM!!!!Originally posted by mystiv:car fuel lah, short and sweet, and easy to find evidence
-
ya, and the fuel we use now is not flammable at all. can use to put out fires from accidents involving hydrogen powered cars.Originally posted by UnheardUnknown:Cannot hydrogen v flammable imagine a car full of huydrogen gt into an accident n KABOOM!!!! -
no, you are actually quite right, the cars that run on hydrogen will emit H2O, which then increases the usable water. But the present techology is such that it uses more energy to create hydrogen than it can provide. But China is actually doing lots of research on hydrogen and might utilise it one day as a energy source.Originally posted by nightzip:hydrogen used in forming H2O?
forgive me, i am crapping..

can make german bomb?

methane in other words.
anyway hydrogen ions can form acids -
Obviously not use pure hydrogen...Originally posted by UnheardUnknown:Cannot hydrogen v flammable imagine a car full of huydrogen gt into an accident n KABOOM!!!!
You will be granted your wish of going to heaven if you do so. -
Hydrogen have lots of uses:
To make your margarine and other solid fats from your liquid fats (hydrogenation) although trans fat are sometimes produced.
As a zero-soot fuel and the most ideal fuel due to its highest energy output per unit mass.
Hydrogen (or more precisely hydrogen-2 isotope known as deuterium) as a source of nuclear fuel for fusion techonolgies although such technologies are still not harnesses effectively yet.
It is not really hydrogen in acids cos it is a proton (or those who study chemistry will know that it is really just a hydronium ion) that gives acids their acidic properties.
That's all about the uses of hydrogen that i can think of right now.
And yes, they used to fill airships with hydrogen, but after the hideous disaster they used helium instead. -
ok... think i got do this qn before...
still got alot, what is the use of CUSO4, NH3, CO2...
all can crap one... related to what u see or have in real life... -
Hydrogen is use for hydrogenation la. just now one person mention... sure got one in polymers topic from alkene to alkane

the car proton?Originally posted by Agenda: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.. -
hw can u question e use of Cuso4Originally posted by Hocklez:ok... think i got do this qn before...
