NO TWO(2) chemicals make hydrogen. Hydrogen is an element found in the Periodic Table.
However, If you react a metal with an acid , it will release hydrogen gas.
Zn + 2HCl = ZnCl2 + H2(g)
So reacting zinc with hydrochloric acid will release hydrogen gas.
Inorganic and organic
A typical glow stick contains hydrogen peroxide and a phenyl oxalate ester, along with a fluorescent dye. When the glow stick is activated by bending it, the chemicals react to produce light.
Hydrogen peroxide and a phenyl oxalate ester are combined inside a glow stick. When these two chemicals mix, they undergo a chemical reaction that produces light.
Hydrogen and oxygen. What is probably meant is which two elements make dihydrogen oxide (water; H2O). The answer remains the same: hydrogen and oxygen.
hydrogen and oxygen are the two elements which make up water
Hydrogen and Helium
alkenes and alkanes
Sulfuric acid, hydrochloric acid, citric acid ...
Inorganic and organic
There are very many. A few examples are: Water (Dihydrogen monoxide) hydrogen peroxide Ammonium Ammonia
Yes you can make hydrogen from water through electrolysis. And also from helium (this happens in the sun)
Since oxygen is an element, it can not be made from chemicals. Instead, it can be separated from compounds. For example, water is made from molecules containing hydrogen and oxygen. When the bond between these two elements is broken by electrolysis, both the oxygen and the hydrogen can be collected.

Water is made of two Hydrogen atoms and one oxygen atom. Usually chemicals are made of molecules so (atoms < molecules < chemicals).
No, these are two different chemicals. Hydrochloric acid, or hydrogen chloride, is a compound of hydrogen and chlorine. Sulfuric acid, is a compound of hydrogen, sulfur, and oxygen.
hydrogen is used to make different chemicals. if you combine it with oxygen it makes water.
