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 ...

The oxidation of the iron is an exothermic process. Heat packs that contain supersaturated sodium acetate: These are reusable, the packs are boiled to dissolve sodium acetate. Inside is a metal ...

Igniting a mixture of Fe2O3 and Al with a magnesium ribbon fuse produces molten iron and aluminum oxide in an impressive exothermic reaction. Pick the beverage can up to show the students. Place 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 ...

Students investigate reactions which produce a gas, form a precipitate, and cause a color change. Students also explore endothermic and exothermic reactions and do an engineering activity to design a ...

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.
