NettetThe answer is that relates to the number of moles of the substance as indicated by its coefficient in the balanced chemical reaction. Thus, 2 mol of H 2 are related to −570 kJ, while 1 mol of O 2 is related to −570 kJ. This is why the unit on the energy change is kJ, not kJ/mol. For example, consider the following thermochemical equation: NettetAl:NiO, Al:CuO, and Al:Cu2O thermite systems were systematically diluted with Ni or Cu to decrease the maximum reaction temperature …

NettetBlack or blue iron oxide (Fe 3 O 4), produced by oxidizing iron in an oxygen-rich environment under high heat, is the most commonly used thermite oxidizing agent because it is inexpensive and easily produced.Red iron(III) oxide (Fe 2 O 3, commonly known as rust) can also be used.Other oxides are occasionally used, such as MnO 2 in … NettetThe thermite reaction can trigger heat or smoke sensors; you cannot do the experiment in a laboratory fitted with smoke sensors.
