Chemical Solution Simple vs APPangea

Chemical Solution Simple helps in preparation of chemical solution by dissolution of solid solute or by dilution of existing solution and in finding of moles, Molar masses, required weights of solutes and volumes of starting solutions. Supported concentration units are Molar (M), mM, uM, g/l, mg/l. Touch the units field to change the units in the aformentioned order. The app includes Molar Mass Analyser. Tap on arrow in the Mw field initiates analysis of chemical formula in the component field and set the value to Mw field. No charge values should be used. Valid examples: Mg(HCO3)2, CaCl2.2H2O, CaCl2*2H2O, (NH4)2Fe(SO4)2.6H2O, Mg(H2PO4)2, C6H12O6. Analyser is case sensitive. Application assigns dot as a decimal separator.

APPangea allows you to learn geography by playing, easily and competing with yourself and with others. The contents of APPangea have been designed by expert teachers who are convinced that geography can be taught in an entertaining, effective way and in accordance with the official curriculum. A topic (Geography of Europe) is grouped into units (eg Relief), and each unit consists of several lessons. Each lesson has questions of different types. Don't be afraid to fail! Pangea will assist you to learn what you do not know in the shortest time. You will find several types of questions, but in most of them there is a map. Can you learn geography without maps? Sometimes the map gives you the information and you have to select the correct question, and other times you have to find the answer on the map itself. Easy, right? We have designed a new learning experience for history and the map has always a great importance. Look at the map for the answer!
