Science Buddies: Can You Change the Rate of a Chemical Reaction?
The ingredients in Alka-Seltzer tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces...
