If I had a bath bomb reacting with water inside of an airtight container, would the mass of the container change? Why?

Our bath bomb released gas when it bubbled. What two characteristics did we test for to narrow down our possibilities of the gasses produced by the reaction?

• Mass and weight

• Density and reaction

• Flammability and mass

• Density and flammability

What were the three gasses we initially considered were being produced by the bath bomb? What characteristics did these three all share in common?

Looking at the chemical structures that made up our ingredients, we determined that the only gas the bath bomb could produce was carbon dioxide (CO2). Why could we not make argon or nitrogen gas from our chemical reaction?

Draw this on a piece of paper please! If you're able to do it on here that's awesome too!

Draw the chemical reaction for our bath bomb atoms. Show atoms of citric acid, baking soda, and water rearranging into carbon dioxide and other particles. Use your workbook pages to find the atomic models!
