Reasoning - How does your evidence support your claim about the experiment? Answer the question with one or more complete sentences for full credit. Optional - Use a sentence stem from the "Reasoning" Box below.
Reasoning:
My evidence supports the claim about the experiment because the change in color of the liquid indicates a chemical reaction occurred. This change suggests that a new substance was formed, confirming that a reaction took place.

Reasoning:
The observation of the baking soda bubbling when the vinegar was added provides evidence that a chemical reaction occurred. This reaction is commonly known as the acid-base reaction between baking soda (a base) and vinegar (an acid). The bubbling indicates the release of carbon dioxide gas, confirming that a chemical change took place.
