we put one scoop of calcium chloride into the baggie with one pippett of fennel red and mixed them together by shaking the baggie. It started to get cold because of the calcium chloride. It smelled like rubbing alcohol. It was also hot pink.
Next was sodium bicarbonate and fennel red into the baggie and mixed them together by shaking the baggie together as well. The baggie turned very hot because of the sodium bicarbonate. It was also hot pink and smelled like rubbing alcohol.
Questions:
1. Calcium chloride with fennel red and sodium bicarbonate with fennel red.
2. Because calcium chloride turns hot
3. It turned hot pink an orange-yellow color. Yes, because we mixed calcium chloride/sodium bicarbonate with fennel red. The white made the red color lighter.
4. No, because they both have slower chemical reaction.
5. No, without water there was no chemical reaction.
6. sodium bicarbonate and then calcium chloride and fennel red and water.
7. We put calcium chloride in a bag with water.
8. Yes because the temp. changed, but then no because other possible chemical reactions and then such as gas bubbles.
