The purpose of this study is to analyze water quality in the sumber maron river located in kepanjen, malang.

Physical and chemical properties of water. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. The chemical formula of a molecule of water is h2o: Changes in the chemical and physical properties of water are one of the causes of water pollution.

When water freezes, it’s still water (h 2 o)—it’s just in a different physical state. The colour of water and ice is, intrinsically, a very slight blue hue, although water appears colourless in small quantities. Selected physical properties of water;

Oxygen is more able to keep them close to it than hydrogen. Liquid water at the same temperature has a density of nearly 1,000 kilograms per cubic meter. This constant plays a very important role in water, being a universal solvent.

Sometimes it can be tricky to know whether or not a chemical reaction has occurred. Water is a colourless and volatile liquid. Vapour pressure (25 °c) 23.75 torr:

Specific conductivitychemical characteristics of water1. Heat of fusion (0 °c) 6.010 kilojoules per mole: These changes are also an indicator of water quality.

Water is one of the few substances existing on the earth's surface in all three forms of matter. Properties of water include its chemical formula h2o, density, melting, boiling point & how one molecule of water has two hydrogen atoms covalently bonded to a one oxygen atom. For example, when you melt ice into water, you can write the process in terms of a chemical reaction.
