Resumen de More Chemistry in a Soda Bottle:: A Conservation of Mass Activity
William D. Bare, Kenneth A. Goldsby, Daniel Q. Duffy, Stephanie A. Shaw
A simple activity designed to illustrate conservation of mass is reported. The activity uses a two-liter soda bottle to contain the products of a gas-evolving reaction. While any number of gas-evolving reactions could be used in this activity, a specific procedure for vinegar and baking soda is given since these materials present nominal hazards and are readily available to K-12 teachers.
