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 ...

All combustion reactions (such as the burning of coal) are exothermic. Incredibly, the reaction between iron and moist air that produces rust is a very exothermic process and generates lots of heat.
