The other answerers are largely right. Burning=oxidation. Oxidation=losing electrons, so you definitely won't get H2-, sorry fddd s. Generally oxidation requires oxygen, but all it requires in this case is an oxidizing agent (something to accept electrons). You can "burn" hydrogen in the presence of Cl2, for example. The Cl then accepts the electrons from hydrogen instead of oxygen, and you get HCl. You can similarly "burn" hydrogen with sulfur, other halogens, etc. Many of those reactions are just as violent as the reaction with oxygen,

Combustion requires the presence of oxygen, so hydrogen will not burn in the absence of oxygen. Hydrogen can also combine explosively with other chemicals including fluorine and chlorine, but it doesn't burn if you just heat it up on its own.

There wouldn't be any flame in the absence of oxygen, which is why dumping sand/water on a flame extinguishes it.

sorry, nothing burns without oxygen (maybe that's why it's
called oxydation)
