With Oxygen:
* Water (H₂O): This is the most common product of hydrogen combustion. It's a very efficient reaction that releases a significant amount of energy.
With Nitrogen:
* Ammonia (NH₃): This is a crucial ingredient in fertilizers and is also used in various industrial processes.
With Carbon:
* Methane (CH₄): This is a potent greenhouse gas but is also a major component of natural gas and a valuable fuel source.
With Metals:
* Metal Hydrides: These are compounds formed when hydrogen reacts with certain metals, like sodium or lithium. They are used in various applications, including energy storage.
Other Reactions:
* Hydrogen can be used to produce electricity through fuel cells. In this process, hydrogen reacts with oxygen to generate electricity, water, and heat.
* Hydrogen can be used as a reducing agent in various chemical reactions.
It's important to note that the specific product of a hydrogen reaction depends on the conditions (temperature, pressure, catalysts) and the other reactants involved.
