Gas Lab __________________ Name Hour Materials: 20 oz. Plastic bottle Baking soda Water 6 raisins Vinegar Plastic spoon Procedure: Fill the bottle ½ full of water. Then, mix 1 scoop of baking soda into the bottle. Place the raisins into the bottle and begin swirling the liquid around. While the water, baking soda and raisins are swirling, 1 partner add vinegar to the bottle. (About ½ the amount of water). Stop swirling the liquid and observe what happens. 1. Record your observations below. 2. Draw a diagram of what you observed. 3. What happened after you added the vinegar? 4. When you see bubbles form, what is this an example of? 5. Define chemical reaction. 6. What are 3 other examples that a chemical reaction has occurred? 7. What kind of shape do gases have within a container? 8. Predict: If we were to heat the soda bottle, what do you think would happen to the liquids and gases inside? 9. This lab also represents gases within a volcano and how they move. The gases within the magma are the following: CO2 CH4 SO2 Ne H2O He H2S N2 Ar Look up what the chemical name is for all of them and the total number of atoms in each molecule. (Some will have only 1).
