Chemical Reaction
We mixed together baking soda and an indicator liquid which was yellow. When they mixed together the temperature changed to red and the temperature dropped. When we mixed in the calcium chloride the temperature became hot and the color went back to yellow. It formed a gas which popped the bag.
Questions
- It had a reaction that formed a different color and the solution became cooler.
- The reaction formed gases and the solution changed color to red and the temperature increased.
- Yes, when water boils it simply changes states of matter not change into a separate substance.
- The reaction was endothermic. When a reaction is endothermic it takes in energy and causes the surrounding area to become cold.
