Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can

Nuclear Power and Its Uses At first nuclear power was only seen as a means of destruction but after World War II a major effort was made to apply nuclear energy to peacetime uses. Nuclear power if made when a nucleus of an atom is split to release a powerful burst of energy. Though technological advancements nuclear power now supplies us with new medical aids‚ a new power source and new ways to do scientific research. New medical advancements are being produced rapidly due to nuclear power. Nuclear
