Water molecules in the atmosphere can form hydrogen-bonded dimers, (H2O2). The presence of these dimers is thought to be important in the nucleation of ice crystals in the atmosphere and in the formation of acid rain. Using VSEPR theory, draw the structure of a water dimer, using dashed lines to indicate intermolecular interactions.

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
