Carbon DiOxide (CO2) is a molecule, which is made up of two different elements.
Water is a compound of two elements: Hydrogen and Oxygen.

Water, which is a compound of hydrogen and oxygen.

Hydrogen is a pure substance because it is an element
Water is not an element, it is a compound. Hydrogen and oxygen are elements, but only if alone.
Hydrogen can be found in water and air.
No. Helium does not react with anything and oxygen is an element: you cannot get an element by combining substances. You can, however, split water apart into hydrogen and oxygen.
Everywhere! Hydrogen is in water!
Distilled (pure) water is a compound; it is composed solely of H2O molecules, with no other substances present.
Actually, water, by hydrogen bonding with itself and not the nonpolar substances excludes the nonpolar substances from hydrogen bonding and turns them into associations with each other. Natural water can hydrogen bond with many polar and charged substances.
Hydrogen* is neither a mixture nor a compound it is a basic element. Compounds are combinations of elements such as H20 (water molecule and 2 oxygen molecules) and mixtures are combinations of substances such as mixing oil and water.

No. The more reactive metals do displace hydrogen. Bases are substances that when adde to water increase the concentration of OH-
No, hydrogen is an element. It is one of the components of water, the other being oxygen.

Coffee is mostly water, H2O. Of water, hydrogen is the most common element, so hydrogen in the most common element in coffee.
