What is the chemical formula of water?
Although its formula (
H
2
O
) seems simple, water exhibits very complex chemical and physical properties. For example, its melting point, 0 °C (32 °F), and boiling point, 100 °C (212 °F), are much higher than would be expected by comparison with analogous compounds, such as hydrogen sulfide and ammonia.
How many atoms are in H2O?
An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has
