Question

Explain what property or law made the students realize their experiment was incorrect. (2 sentences required) I know its a science question but no one in chemistry will help so I thought Id ask here and see the results

Answer 1

You did not specify what the experiment is so I don't think anyone will have sufficient information to help. In addition, helpers are forbidden from answering or helping with test questions posed by askers. @iamdumb

Answer 2

1. Pour 100 g vinegar into a flask. A flask looks like this.
2. Measure the temperature of the vinegar.
3. Add 10 g of baking soda to the flask.
4. Observe as the contents of the flask fizz (produce bubbles).
5. Measure the temperature of the contents in the flask and observe any change in temperature.
