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 ...

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.

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 ...

The copper-based catalyst is designed to be effective at lower temperatures (450-650 °F). The low temperature reactor has a lower reaction rate, but converts a very high percentage of the remaining CO ...

This fun and bubbly experiment combines peroxide, yeast, and other stuff to demonstrate catalysts and exothermic reactions. Watch the heat-producing mixture bubble and overflow for up to half an hour.

Science presenter Jon Chase demonstrates an exothermic and an endothermic reaction, and explains how temperature changes can be used to identify which reaction is which. The exothermic reaction is ...

Many experiments, including catalyst preparation ... a low reaction temperature favors the exothermic methanol synthesis reaction but not the endothermic RWGS reaction. More information: Wei ...
