Last updated over 3 years ago

16 questions

Instructions

Watch the video of the chemical reaction between alka seltzer and water. This reaction will prove our new concept of the Law of Conservation of Mass. 

Conservation of Mass Demonstration

Chemical Formulas

Look at the chemical formulas below and decide if they support the law of conservation of mass. This means that the amount of each atom will be the same to the left and right side of the arrow. (before and after the chemical reaction) Select YES if they are equal, select NO if they are not.
