The scientific word for burning is combustion. All combustion reactions give off heat into their surroundings. So they’re described as exothermic reactions. But there are other exothermic ...
Incredibly, the reaction between iron and moist air that produces rust is a very exothermic process and generates lots of heat. Unfortunately, this particular reaction takes place so slowly that ...
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 ...
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 ...
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 ...
Question: Why does concrete get hot when it is curing? Answer: Simply put, water plus aggregates (gravel, sand, stone), plus cement (such as Portland cement) start a chain of chemical reactions called ...
