Hydrogen can be found in all forms of water, and all substances that contain water (including humans).
This is because the chemical formula for water is H2O. I hope this answers your question!
Carbon and hydrogen are found in all organic compounds. Oxygen and nitrogen are also commonly present in organic molecules.
Hydrogen and carbon, of course!

Hydrogen is found in lots of thing. Water contains hydrogen as does hydrogen peroxide.
This ion is the hydrogen cation.
The hydrogen ion (H+) is found in all acids. When an acid dissolves in water, it releases hydrogen ions, which give acids their characteristic sour taste and ability to react with metals.
carbon is found in all organic materials from phospholipid bilayers (cell membranes) to chloroplasts also hydrogen
It costs nothing, it is found in all forms of life.
