1. Below are two simple diagrams of a sodium ion and a chloride ion. Note the charge they carry. In the space aroun
draw three to four water molecules per ion to show how the water molecules interact with the them:
Na+
2. Explain the formation of hydrogen bonds between water molecules
4. Why does ice float on water?
3. Explain why aquatic environments have relatively stable temperatures:
other require a lot of
energy to break. This is why water
has a much higher boiling point than
hydrogen sulfide
5. Explain why water has a high surface tension:
CI
6. Why does hydrogen sulfide have a much lower melting point and boiling point than water?
