I'd like to change some money https://www.canadabusinessdirectorylistings.com/stmap_24pkcjjq.html?gase... nizoral a-d sampon Gunpowder is a mixture of relatively innocuous chemicals: saltpetre, charcoal and sulphur. The charcoal and sulphur act as fuels, while, given a suitable push, the nitrogen, oxygen and potassium in the saltpetre break their bonds, allowing the liberated oxygen to ignite the other ingredients and produce an expanding wave of gas. Plenty of nitrate salts do the same, often with greater power (as in the typical car bomb, which is made of ammonium nitrate mixed with fuel oil).
