is water a mixture

E.g. sugar solution, dry air etc. So, from the above discussed definitions, it is clear that the water is a compound and not a mixture because it is made up of. Pure water that contains only H2O molecule is a compound. It is composed of two different elements i.e. hydrogen and oxygen that bond chemically in a fixed. Water is not a mixture but a compound. It has elements hydrogen and oxygen which are combined chemically with two hydrogen and one oxygen atoms. These cannot be. Hint: Water is a molecule that is made up of two molecules of hydrogen and one molecule of oxygen. And a mixture is referred to as a substance that is made. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms.

18 karat gold pure substance or mixture

18 karat gold is a mixture.It is 75% gold and 25% (usually) copper.Caratage is the measurement of purity of gold alloyed with other metals. 24 carat is pure gold with no other metals.
