"We all agree that oxygen is one of the most vital elements required to sustain life. It is the third most abundant element in the universe and makes up nearly 21% of the earth's atmosphere. Oxygen had been produced by several chemists prior to its discovery in 1774. This app highlights one of the various methods of preparing oxygen in which hydrogen peroxide is decomposed in the presence of manganese dioxide. Exploration of this method through this app will bring you a video which illustrates the assembly, process and the molecular view of the actual chemical reaction happening in the flask. The app package also includes important key-terms, access to additional resources as links, and also an interactive quiz at the end for evaluation. The section on images showcases the learning objectives in a nut-shell.At Designmate, we strive to make learning exciting for you.
