An overview about the chemical element Boron
By: Melanie Grimes
Boron was named from borax, the mineral that contains boron in large quantities. It is a component of the gemstone tourmalines. It was discovered by the French chemists Joseph-Louis Gay-Lussac and Louis-Jaques Thnard in 1808, the same year that it was also discovered by the...

Thermodynamics of chemical reactions has three basic laws which govern the behavior of chemical reactions. Classical thermodynamics Deals with chemical systems under equilibrium conditions. Two other areas which are related to thermodynamics. These are statistical thermodynamics and non-equilibrium thermodyamics.An example of a system that...
