    DOWNLOAD  $0.99



    ‘Law of Conservation of Mass’ is an outstanding chemistry app for middle school students that lets them explore that irrespective of chemical changes, the total mass of any of the substances remains unchanged during a chemical reaction.
    The salient features of the app include:
    • An animation video which showcases the physical mixing of iron filings and sulphur powder followed by the heating of the mixture which leads to the formation of a black coloured iron sulphide. Calculation of the total mass, before and after the reaction, helps you verify the law of conservation of mass.
