The carbon dioxide is trapped by detergent to form bubbly lava, which flows down the side of the model because carbon dioxide is more dense than air. However, sometimes you'll want to explain or write the chemical reactions that occur to produce the carbon dioxide. Here's a look at ways to write the reactions.
