Iron oxide, aluminum, and a catalyst ... in an exothermic reaction. The demonstration shown in this video is very dangerous. Do not attempt to perform this demonstration. The combustion of methane is ...

Temperature, concentration, pressure and the use of catalysts affect reaction rate. Heat energy changes in chemical reactions - Edexcel Exothermic reactions in solution give out energy and the ...

Catalysts are useful because they do not get used up during a reaction. Exothermic and endothermic reactions Exothermic reactions release energy into the surroundings, so they usually feel hot.
