In this particular article we will learn about hydrobromic acid and the process of preparation of hydrobromic acid. First a brief introduction to hydrobromic acid. Hydrobromic acid is an inorganic acid also known as a mineral acid. It's composed of hydrogen and bromine and is the bromine analogue of the more famous hydrochloric acid. Now hydrogen bromide is actually a gas but when it’s dissolved in water we call it hydrobromic acid. Azeotropic hydrobromic acid has a boiling point of about 124.3 Celsius at atmospheric pressure and corresponds to a concentration of 47.6%, although variations of a couple of percent aren't uncommon. It can be used for many of the same purposes as hydrochloric acid but because it is generally more expensive it is more often used when bromine or bromide itself is specifically needed. It's mostly used to make organobromine compounds and we ourselves used it this way sometime ago to make bromoalkanes for making grignard reagents....
In this article we'll be discussing the evolution of computing - more specifically, the evolution of the technologies that have brought upon the modern computing era. We will also see the full form of computer. Full form of computer Commonly Operated Machine Particularly Used for Technology Education and Research History of computing Many inventions have taken several centuries to develop into their modern forms and modern inventions are rarely the product of a single inventors efforts. The computer is no different, the bits and pieces of the computer, both hardware and software, have come together over many centuries, with many people and groups each adding a small contribution. We start as early as 3000 BC with the Chinese abacus, how is this related to computing you ask? The abacus was one of the first machines humans had ever created to be used for counting and calculating. Fast forward to 1642 and the abacus evolves into the first mechanical adding m...
