Kent's HD Chemical Demonstrations

 

HD 2010 Dry Ice And Magnesium Magnesium ribbon and turnings are placed into the center of a block of dry ice and ignited. This energetic reaction produces Magnesium Oxide and elemental carbon. 2Mg + CO2 →C +2MgO	Bubbles Filled with Fog   Dry ice is dropped into a flask and a one holed rubber stopper with a thistle tube on the end is dipped into soap. The fog from the dry ice fills the bubble and can be held and even tossed using microfiber gloves.
Creating a Monster Soap Bubble Dry Ice for Halloween Dry Ice (solid carbon dioxide) is dropped into a large tub of warm water. A cotton rope is soaked in soap and slowly dragged across the rounded lid. As the dry ice sublimes (turns from a solid to a gas) the bubble expands and eventually	Ammonium Dichromate Volcano Ammonium Dichromate is a somewhat compact orange solid that when heated decomposes into a green solid Chromium(III) Oxide( that appears to grow in size) along with nitrogen and stream. You can see why this reaction is called a volcano reaction. The reaction (NH4)2Cr2O7(s) → Cr2O3(s) + N2(g) + 4 H2O(g) (ΔH=−429.1 kcal/mol)
