A group of students do an activity with baking soda and vinegar. The steps of the activity are listed below: 1. Pour 100 g vinegar into a flask. 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. After the fizzing stops, the students determine that the liquid in the flask has a mass of 105 g. The students realize their experiment was incorrect.

law of conservation of mass.

if you had 100 g and added 10 g, but only measured 105 g, where did the other 5 g go?

HINT: write an equation for the reaction, make sure you label the phases of the products.
