Question
Maribel and Isabela were conducting the following experiment:
Place and empty water bottle on the table and remove the lid. Carefully pour 10 ml of vinegar into the bottle.
Open up the mouth of the balloon and have your partner spoon 1 teaspoon of baking soda into the balloon.
Without spilling any of the baking soda, stretch the mouth of the balloon over the mouth of the bottle.
Turn the balloon completely upright so that the baking soda inside the balloon pours into the bottle with the vinegar.
The baking soda looked like it dissolved in the vinegar. Maribel and Isabela watched as the balloon expanded and filled with a gas. Was this a physical or chemical change and why?
Responses
It was a chemical change because a gas was produced.

The correct response is:
**It was a chemical change because a gas was produced.**
In this experiment, a reaction occurs between the vinegar (acetic acid) and the baking soda (sodium bicarbonate), which produces carbon dioxide gas. The production of a gas is a key indicator of a chemical change. Additionally, while the baking soda may appear to dissolve initially, the reaction with vinegar involves a chemical transformation, not just a physical change. The generation of gas and the formation of new substances indicate that chemical changes are occurring.
