Endothermic Reaction

Hey everybody!!  Zelle and I are doing endothermic reactions for Test 6.  We will have a video posted soon of our actual experiment and all of our materials and results. 


Endothermic: "within-heating" --> describes a process or reaction in which the system absorbs energy from the surroundings in the form of heat (takes in heat and doesn't produce it... so it is a cold reaction)


Materials

~ 25 ml of acetic acid
~15 g of baking soda
~ a styrofoam cup
~ a thermometer
~ stirring rod
