Students were asked to set up an experiment. Each group was given 4 flasks, and each flask was set up according the table above. The flasks were sealed. PART A If the flasks were left sealed for a week, flask number would most likely have the largest amount of CO2? PART B would help reduce the amount of carbon dioxide produced from your answer to

Answer 1

In order to accurately answer the questions regarding the flasks and carbon dioxide (CO2) production, I’ll need some more context related to the contents of each flask as described in the experiment. Typically, in similar experiments, flasks may contain different types of organisms, such as plants, yeast, or bacteria, or might differ in conditions like temperature, light, or the presence of nutrients.

PART A

If you were to determine which flask would most likely produce the largest amount of CO2 after being sealed for a week, consider the following common scenarios:

• If one flask contains yeast: Yeast ferments sugars into alcohol and CO2, especially in anaerobic (sealed) conditions.
• If another flask contains plants: Plants typically undergo photosynthesis during the day (taking in CO2) and respiration (producing CO2) at night. However, in a sealed condition, the production of CO2 at night would be offset by some CO2 absorption during the day.
• If one flask has no organisms: This would likely produce no significant CO2.

If you have a flask with yeast, that flask would likely exhibit the highest levels of CO2 production after a week due to fermentation.

Answer for PART A:

The flask with yeast would most likely have the largest amount of CO2 after a week.

PART B

To help reduce the amount of carbon dioxide produced from the flask that likely produced the most CO2 (the yeast flask), we can consider several strategies:

1. Reducing Sugar Concentration: Since yeast ferments sugars into CO2, decreasing the amount of sugar available could significantly lower CO2 production.

2. Temperature Control: Yeast activity increases with temperature. Lowering the temperature may slow down fermentation and reduce CO2 production.

3. Oxygen Availability: While yeast can ferment anaerobically, providing enough oxygen can shift the metabolism to aerobic respiration, which produces less CO2 compared to anaerobic fermentation.

4. Dilution or Lower Concentration: Introducing water or other substances that dilute the concentration of sugars can inhibit the fermentation process.

Answer for PART B:

To reduce the amount of CO2 produced, you could decrease the sugar concentration or manage the temperature in the flask.
