Hydrogen consists of an Atomic nucleus and one proton. It is a gas and it's clear.
Advantage - It provided more lift than helium. Disadvantage - It was highly flammable. hydrogen's flames are colourless but look like fireworks
As far as I know: yes! They involve hydrogen bonded to an electronegative element (like oxygen). This Hydrogen in the molecule is then attracted to another electronegative element (like oxygen, nitrogen etc)
H2O2 or hydrogen peroxide has the two hydrogen atoms on either end of two bonded oxygen atoms. The hydrogen atoms are off at an angle in the same direction from the oxygen atoms ( non linear) and 110 degrees offset from each other. H-O-O-H
calcium hydrogen phosphate look.. http://www.chemindustry.com/chemicals/0522656.html
It's just what it sounds like: hydrogen and bromine.
it looks like a space filling model .This shows the realistic representation of hydrogen and how closely bonded they are.
Example sentence - The answer to the first question on the test is hydrogen.
It is transparent and colorless, you can't see it.
The chemical formula of hydrogen sulphide is H2S.
HCl is hydrochloric acid. That might look like a one, but it is a lower-case L. H=Hydrogen, Cl=Chlorine.HCl is hydrochloric acid. That might look like a one, but it is a lower-case L. H=Hydrogen, Cl=Chlorine.
It doesn't look like it. Hydrogen peroxide is highly corrosive of a wide variety of materials, especialy when dried.
Hexane is C6H14 and looks like 6 carbon atoms strung in a zigzag line with 2 hydrogen atoms attached at each carbon and an endcap hydrogen atom each at the ends of the chain.
Electric cars can be charged with electricity, where as hydrogen cars use a fuel cell that would have to be refilled at a refueling station. It doesn't look like there will be many hydrogen cars on the road until 2020. Take a look at this article: http://www.renewable-energy-news.info/electric-vs-hydrogen-the-future-of-green-cars-battle-it-out/
One bond and 6 unpaired electrons around fluroine.
It looks like an oil, somewhat like olive oil does. Adding hydrogen saturates the carbon to carbon bonds making it a solid.
H2+O2=H2O is what a synthesis reaction would look like or also is the creation of water by combining hydrogen with oxygen
Hydrogen sulphide, H2S, is a colorless and poisonous flammable gas.
