Question

when baking soda is added to vinegar, the solution produces a gas (carbon dioxide). a student is trying to see if there is a relationship between the amount of baking soda added and the amount of gas produced. he added different amounts of baking soda (0.5 g - 3.0 g in 0.5 g increments) to 25 ml of vinegar in a test tube, and collected the gas in a balloon. the data is graphed below. use the graph to answer the next two questions. 3. what is a valid conclusion to draw from this data? a. the amount of gas produced continues to increase as the amount of baking soda increases. b. adding more baking soda than 2.0 g does not result in additional gas production. c. the amount of gas produced depends only on the amount of vinegar in the test tube. d. there is no relationship between the amount of gas produced and baking soda added.

Explanation:

• Analyze each option:
• Option A: After \(2.0g\) of baking soda, the gas amount plateaus, so it doesn't continue to increase.
• Option B: At \(2.0g\) baking soda, the gas volume reaches a maximum (\(\approx500\)) and doesn't increase with more baking soda (\(2.5g\) and \(3.0g\) give same volume).
• Option C: The experiment varies baking soda (independent variable), not just vinegar.
• Option D: Clearly, there is a relationship (gas increases with baking soda up to \(2.0g\)).

Answer:

B. Adding more baking soda than \(2.0g\) does not result in additional gas production.
