The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
In addition, the mercury arc produces substantial amounts of short wave UV which is extremely hazardous to anything living. The outer glass normally blocks most of this from escaping. Some lamps are actually designed with fusable links that will open after some specified number of hours should ...
most organic corrosion inhibitors are expensive and hazardous to the environment and public health. Organic compounds with heterocyclic and aromatic heterocyclic rings have stronger inhibition effects in acidic solutions9,10,11,12,13. The adsorption of organic chemicals is determined by chemical (the for...
