Water is an oxygen hydride consisting of an oxygen atom that is covalently bonded to two hydrogen atoms. It has a role as an amphiprotic solvent, a mouse metabolite, a Saccharomyces cerevisiae metabolite, a member of greenhouse gas, an Escherichia coli metabolite and a human metabolite. Water appears as 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.
