PLEASE HELP IM REALLY STRESSED OUT AND I JUST NEED SOMEONE TO DO THIS FOR ME! IK ITS ALOT SORRY! In this task, you'll determine whether a reaction between baking soda and citric acid is an endothermic reaction and whether it can be used in a cold pack. Estimated time to complete: 15 minutes Use this information to answer the questions that follow: To begin the experiment, Xavier washed his hands and put on safety goggles. He then measured 120 milliliters of tap water, 2.5 milliliters of baking soda, and 2.5 milliliters of citric acid. The initial temperature of the water was 23.5°C. Next Xavier added the baking soda and citric acid to the water. The mixture immediately began to bubble vigorously, which lasted for about 30 seconds. The new temperature of the mixture was 17.7°C. Part A: is a chemical reaction taking place during Xavier's experiment? How do you know?
Part B: Did the chemical reaction absorb or release energy? How do you know?
Part C: Could this chemical reaction be used inside a cold pack or inside a container designed to keep a drink cold? Justify your answer.
