• Oxygen and sodium hydroxide

• Water, carbon dioxide, and sodium acetate

How much vinegar is used in each flask during the experiment?

• 50 grams

• 100 grams

• 25 grams

• 75 grams

Which flask contained the most sodium bicarbonate?

• All flasks had the same amount

• Flask 1

• Flask 2

• Flask 3

What was observed in the flask with the least amount of CO2 gas produced?

• It had the most leftover baking soda

• It was completely clean with no residue

• It had the most vinegar left

• It produced the most gas

What was a notable observation about the third flask?

• It produced no gas

• It had no reaction

How many moles of vinegar were present in the first flask?

• 0.179 moles

• 0.417 moles

• 0.250 moles

• 0.500 moles

Why did the second and third flasks produce similar amounts of gas?

• They had the same amount of baking soda

• They had the same amount of vinegar

• They were not reacting

• The reaction ratio was 1:1
