Water (chemical formula: H?O) is a substance composed of two elements: hydrogen and oxygen. It is generally non-toxic. According to its chemical formula, people give water the following nicknames: hydrogen oxide, dihydrogen monoxide; analogy to the naming rules of other compounds in groups VIA and VIIA: hydroxide acid, acid oxygen; analogy to the naming rules of metal hydroxides (bases): hydroxide Hydrogen, caustic hydrogen, hydroxyl hydrogen, basic hydrogen. It is a colorless and odorless transparent liquid under normal temperature and pressure, and is the source of human life. Water includes natural water (rivers, lakes, atmospheric water, sea water, groundwater, etc.) and artificial water (water obtained by combining hydrogen and oxygen atoms through chemical reactions). Water is one of the most common substances on the earth. It is an important resource for the survival of all life, including inorganic compounds and humans. It is also the most important component of living organisms. Water played an important role in the evolution of life. It is a non-renewable resource in a narrow sense and a renewable resource in a broad sense.
