    The identity of the unknown solid white compound is determined and verified through a series of tests which uncover physical and chemical properties necessary for identification. A new sample of the same compound is then created to further prove the accuracy of the identification. The compound must be identified in order to be used. For example, KCl is used in medicine, scientific applications, and food processing. It also tastes a lot like sodium chloride, and is the main ingredient in dietary salt substitutes.1 The other possible compounds substance 634p could be have very different properties and uses though they look similar.

There are thousands and thousands of different types of bacteria in the world and one group of bacteria, Gut Flora, has become evident in the bacterial community for being beneficial. Gut Flora is a group of bacteria that consists of microorganisms that live in the digestive tracts of animals. A healthy adult has around a trillion microbes of these bacteria in the gut. These bacteria have a vital role in the body and without them people probably would not survive. It is essential that people take care of their gut flora because a damaged gut flora has been the main cause of many diseases. Despite the fact that gut bacteria may have some harmful effects on humans and animals, the existence of gut bacteria within the intestinal tract result in the gain of many benefits for the bacteria and the host.…
