Here are some possibilities:
* Water (H₂O): This is the most common example. Water is made up of two hydrogen atoms and one oxygen atom.
* Acids: Many acids contain hydrogen. For example, hydrochloric acid (HCl) and sulfuric acid (H₂SO₄).
* Hydrocarbons: These are molecules that consist of only hydrogen and carbon. They are found in fuels like gasoline and natural gas.
* Many organic compounds: Organic molecules, like sugars, fats, and proteins, often contain hydrogen.
* The Sun and other stars: Hydrogen is the most abundant element in the universe and makes up a significant portion of stars.
If you can give me more context, I can provide a more specific answer! For example:
* Are you looking for a list of everyday things that contain hydrogen?
* Are you interested in the chemical properties of hydrogen?
* Or perhaps you are asking about the role of hydrogen in the universe?
Let me know, and I'll be happy to help.
