Thermite Lab Writeup
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
