6. Measure exactly 35 mL of vinegar in the graduated cylinder. 35 Pour the vinegar into the baggie.

7. Mass the soufflé cup. Add 3.5g of baking soda into the soufflé cup. 3.5 g Pour the baking soda into the baggie. Quickly close the bag.

8. When you dump the baking soda into the vinegar... The chemicals react to form bubbles of carbon dioxide

9. Be careful to close the baggie quickly or your CO ₂ will escape CO 2

10. Are you ready to begin your experiment? CO 2
