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 ...

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 ...

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 ...

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 ...

Chemical equations are the symbolic representations ... In the types of reactions knowing which reactions are endothermic and which are exothermic is one of the most important parts.

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.
