Question

1 pts Steel wool wetted with vinegar is stuffed into a narrow mouth round glass bottle. A rubber balloon is then sealed over the mouth of the bottle. After several hours, the balloon inflates into the bottle in an inverted manner. What happened

Answer 1

Here's what I find

Step-by-step explanation:

The aqueous acid causes the iron to react with the oxygen in the air.

The reaction is probably

2Fe + O₂ + 4H⁺ ⟶ 2Fe²⁺ + 2H₂O

The removal of oxygen causes the pressure inside the bottle to decrease.

The greater outside pressure causes the balloon to inflate into the bottle in an inverted manner.
