Black hydrogen is condensed-phase molecular hydrogen that has become opaque to visible light due to changes in its electronic structure. Complete opacity to visible light sets in only at very high pressures (hundreds of gigapascals) and is often achieved using diamond anvil cells.

What is the colour change when copper oxide is added to hydrogen?
Copper oxide is black and when reacted with Hydrogen is REDUCED to elemental copper which is "copper" colored or red-brown
What are coals characteristics?
it is black, and comes in clumps like rocks. It is made up of carbon and hydrogen therefore being called a hydrocarbon
Who created hydrogen?
how made hydrogen how made hydrogen how made hydrogen how made hydrogen
What does h stand for in h20?
Hydrogen. The lightest element.
What is difference between hydrogen sulfide and hydrogen sulphide?
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
What is a black tarry compound of hydrogen and carbon?
Bituman is the compound of Hydrogen and Carbon
What is the identification test of hydrogen gas?
Place a piece of Lead acetate into the possible source. If Hydrogen Sulfide is present, the paper will turn black.
What is the colour change when copper oxide is added to hydrogen?
Copper oxide is black and when reacted with Hydrogen is REDUCED to elemental copper which is "copper" colored or red-brown
Does silver get rusty?
Impossible; but silver can react with the H2S (hydrogen sulphide) from the atmosphere and the surface become black. This black sulphide can be easy removed.
What has the author Edward Daniel Black written?
Edward Daniel Black has written: 'The overvoltage of hydrogen in sulfuric acid at a dropping mercury cathode--'
How is black pigment produced in the sim tube?
the organism inside the tube has produced hydrogen sulfide
What color is a hydrogen atom?
Color coding is not the most usual way of presenting the periodic table of elements, which when it was devised by Mendeleev, was strictly black and white. If you are looking for hydrogen on the table, hydrogen is the first element.
Why is platinum coated with platinum black used in the standard hydrogen electrode?
The platinum black provides a very high surface area that promotes the speed of reaction at the electrode and thereby virtually eliminates overpotential at the standard hydrogen electrode. An overpotential would lead to misleading values of potential of other electrodes compared with a standard hydrogen electrode that manifested overpotential.
How do you bleach hair from black to blonde?
Use either: Honey Hydrogen Peroxide Lemon Juice Tea
Why hydrogen peroxide is stored in wax lined black colored bottles.?
The purpose is to avoid decomposition of H2O2.
Could you see a black dwarf?
No, you cannot. As the name suggests, a "black" dwarf is "black" because it has stopped burning hydrogen/helium for fuel, and is now not producing energy and has cooled to the point that it no longer glows.
Is there life in a black hole?
There might be because a black hole has Hydrogen and Helium. These chemicals have bacteria and bacteria is a living thing. So there might be, I'm not saying there is totally.
