The Chemistry of Water

1. Describe how water molecules are bonded.
Each hydrogen nucleus is bond to the central oxygen atom by a pair of electrons that are shared between them.

2. Describe how the positive and negative charges of water are distributed.
The positive and negative charges are not distributed uniformly.

3. Describe the chemistry of water that allows an insect to walk on water.
Due to surface tension, a molecule within the bulk of a liquid experiences attractions to neighboring molecules in all directions, but since these average out to zero, there is no net force on the molecule.

4. What is unique about water and its density?
It varies depending on its state of liquid, solid, or gas.
