How To Balance Equations - Part 1
Learn the basics about balancing equations, as a part of chemical calculations. The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical...
Professor Dave Explains
Energy Diagrams, Catalysts, and Reaction Mechanisms
It's time to learn a little more about a chemical reaction. How do molecules have to be arranged and how much energy do they have to collide with? What's a catalyst? Lots of great tidbits in this one.

Hydrating anhydrous copper (II) sulphate (white) by dripping water.
The blue colour of copper (II) sulphate is due to the presence of so-called water of crystallisation in the crystal structure. Dripping water onto the anhydrous form rehydrates the compound, giving the blue colour
