Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.


WATER is a clear, nontoxic liquid composed of hydrogen and oxygen, essential for life and the most widely used solvent.Include water in a mixture to learn how it could react with other chemicals in the mixture.


What is the composition of water? Everyone is very familiar with water. We observe it as rain and snow and can see it in the oceans, lakes, rivers, and streams. Although the water in our bodies is not as apparent, recognize that most of our weight is made up of water.


The composition of water is 2H2O, commonly mistaken as H2O. H2O is wrong because oxygen can not exist as a single molecule and therefore must have two.


What Are the Components of Water? Water is comprised of two parts hydrogen and one part oxygen, giving it the chemical formula H2O. Water is the most common chemical compound found on planet Earth and the most vital compound for the formation and survival of life.


Chemical uses. Water is widely used in chemical reactions as a solvent or reactant and less commonly as a solute or catalyst. In inorganic reactions, water is a common solvent, dissolving many ionic compounds, as well as other polar compounds such as ammonia and compounds closely related to water.

The physical and chemical properties of seawater vary according to latitude, depth, nearness to land, and input of fresh water. Approximately 3.5 percent of seawater is composed of dissolved compounds, while the other 96.5 percent is pure water. The chemical composition of seawater reflects…


Water is composed of two atoms of hydrogen and one atom of oxygen. Because of this composition, water has unique properties that has made it essential to life on the planet. The molecules in water form hydrogen bonds. Oxygen atoms in water have a slightly negative charge whereas hydrogen atoms are slightly positive.


The chemichal components of water are H20. Two hydrogen molecules and one oxygen molecule.
