Trinitrotoluene (TNT) -
Trinitrotoluene is better known as it's initials TNT. It is an important explosive, since it can very quickly change from a solid into hot expanding gases. Two moles of solid TNT almost instantly changes to 15 moles of hot gases plus some powdered carbon, which gives a dark sooty appearance to the explosion. This is where another explosive. TNT is explosive for two reasons. First, it contains the elements carbon, oxygen and nitrogen, which means that when the material burns it produces highly stable substances (CO, CO2 and N2) with strong bonds, so releasing a great deal of energy.
Nitroglycerin -Nitroglycerin is an oily, colourless liquid, but also a high explosive that is so unstable that the slightest jolt, impact or friction can cause it to spontaneously detonate. Since the molecule contains oxygen, nitrogen and carbon, when it explodes a lot of energy is released as the atoms rearrange to form new molecules with strong, stable bonds, like N2 and CO. http://www.ch.ic.ac.uk/rzepa/mim/environmental/html/nitroglyc_text.htm%20Hexahydro
