    and here is the question: 3. Based on your observation, was the reaction endothermic or exothermic? Explain your answer using complete sentences.

    I said something along the lines (to avoid plagiarism problems) : that since endothermic is taking IN heat that it has to be exothermic.

    what do you think in the video Endothermic Reaction - Baking Soda and Vinegar- the temperature in the thermometer decrease?

    yeah I agree with Cuanchi We can observe a temperature drop in that reaction. Which means the reaction absorbs the heat. Heat is absorbed while the surrounding is cooled. Therefore it is an endothermic reaction.

    Yup, we can observe the temp and drop in a reaction thats displayed, so it can absorb heat with the outside cold. Fan?

    @mosuechick0012 its endothermic because of the temperature drop because you know that heat was being taken from the surroundings. That's how you know. Also if you see something heating up I/e increase in temp you know it's exothermic because heat is being released into the surroundings.
