While you're watching, look out for the different household items which can be used for exothermic and endothermic reactions. A Bunsen burner flame is produced by burning methane gas. The ...

Heat packs that contain iron and water packets: Exposing the solution to air results in the oxidation of the iron (creates rust). The oxidation of the iron is an exothermic process. Heat packs that ...

Two dry solids --- barium hydroxide and ammonium nitrate --- are mixed to produce an endothermic reaction. The temperature of the mixture drops approximately 45oC and is cold enough to freeze the ...

Iron oxide, aluminum, and a catalyst are placed in a flowerpot. The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration ...
