What is the black powder used to melt ice bergs?
The black powder used to melt icebergs is typically a mixture of soot and oil. When spread over the surface of the iceberg, the black color absorbs more sunlight, increasing the rate at which the ice melts.
Chemical name of so2?
The composition varies depending upon the hydrocarbon burned. However, by definition, soot is the black solid or tarry substance produced during hydrocarbon combustion. Analysis has revealed the presence of some smaller molecular weight liquid hydrocarbons such as C8 compounds to C20 but for the most part more stable polyaromatic hydrocarbons are formed. These polycyclics have been implicated in cancer. They are known carcinogens.
