Woodturning - The Exothermic Epoxy 11 Wood Spiral Vase FailAs the title says things didn't go according to plan on this piece, I had a major resin fail !! Moisture condensed inside I ...
Usually, mechanochemical reactions between solid phases are either gradual (by deformation-induced mixing), or self-propagating (by exothermic chemical reaction). Here, by means of a systematic ...
It includes observations and conclusions that students are meant to make on their own. Students will conduct two chemical reactions. In the first, the temperature will go down (endothermic) and in the ...
There probably aren’t many people out there who aren’t aware of what thermite is and how it demonstrates the power of runaway exothermic reactions. Practical applications that don’t involve ...
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 ...
