This short video whistles through most of the chemistry of cobalt complexes. The structures of the complexes and the thermodynamic and equilibrium factors are discussed briefly. The acidity of hexaaqua cations is considered, together with the dual role of ammonia solution as a Bronsted base and as a ligand. This is just one of several videos covering the chemistry of transition metals and their compounds.

This video lesson hows the use of a magnet to separate a mixture of sulfur powder and iron filings.

In this video lesson, Mr. Scullion demonstrates a reacting mass problem involving volume of nitrogen. Try the problem out on your own prior to finding out the solution.

The title says it all. 50 times bigger and 4 times faster. However, do consider this as evidence of the incredibly small size of atoms/ions. For the growing crystals to have such flat surfaces and razor-sharp edges - the building blocks have to be tiny... OOOOOOoooooooooo-----------------. Otherwise we'd see the bumps!
