Is trinitrotoluene an element or compound? Trinitrotoluene (TNT), a pale yellow,solid organic nitrogen compoundused chiefly as an explosive, prepared by stepwise nitration of toluene. Why picric acid is called an acid? We know phenol shows acidic nature. 2,4,6-Trinitrophenol is highly acidic in...
A luminescent bacterial strain, Vibrio sp., isolated from Mediterranean sea has been employed in BL assays of heavy metals, organic chemicals (benzene, toluene, ethylbenzene, xylene), and a wide range of pesticides. The use of this strain represents an improvement, with respect to the main ...

A photosensitive element, and a process for forming a high density photo mode image with it, is disclosed comprising a support, an image forming layer comprising an image forming substance, preferably carbon black, a photopolymerisable layer and a cover sheet. Optionally a release layer can be ...
Boiling water on a stove occurs when thermal energy from the heating element is transferred to the pot and in turn to the water. When enough energy is supplied, liquid water expands to form water vapor and the water boils. An enormous amount of energy is released when water boils. Because...
