Chemical Properties<br />
The chemical properties of water are determined by the polarity of the water molecule and the strength of the hydrogen bond.</p>
<p style="text-align: justify;">
Water is a polar molecule, meaning that the electrons in the molecule are not evenly distributed. One end of the molecule is positively charged (the hydrogen atoms) and the other end is negatively charged (the oxygen atom). This polarity allows water to dissolve many different types of molecules.</p>
<p style="text-align: justify;">
The hydrogen bond is the attraction between the hydrogen atom in one water molecule and the oxygen atom in another water molecule. This bond is very strong and allows water to dissolve many different types of molecules.</p>
