Explain the properties of water and what properties of water are essential to life on both the microscopic and macroscopic scale.  Be sure to use all relative terms and examples of application of these properties in living things or in their environment.

Chlorine is an element with the symbol Cl. Draw and label atomic structure of chlorine indicating the number and locations of protons, neutrons and electrons in one atom of chlorine.

In 300-400 words (which is about 20 sentences, 1 longer paragraph, or 2 shorter paragraphs), please use your own words to summarize the chemical properties of water and explain two or more reasons why living things need water.
