In this home-science how-to from Household Hacker, we learn how to create an exothermic reaction by combining sulfur with iron, producing iron sulfide in the process. For all of the details, including step-by-step instructions, as well as to see what happens when these two elements meet, watch this video guide.
Sugar (a carbohydrate) is dehydrated with concentrated sulfuric acid. Since a carbohydrate was once considered just hydrated carbon, if you remove the water, carbon would be left over. The acid rips the water out of the sugar and the heat generated by this reaction causes the water to turn to steam. A black mass of carbon is produced.
Watch this video to learn how to make a penny operated nitric acid fountain. Nitric acid acts upon copper to yield nitric oxide in an exothermic reaction. The expanding gas displaces water from another flask; actually bubbles in this set up. When the gas cools, the water is drawn back into the flask, dissolving the nitric oxide and forming a blue solution with the copper ions still there. Very cool science experiment with a neat reaction.
