Question

Hi, I'll medal and fan if someone can help me with a question I don't understand.

Answer 1

Here's the link to the video https://www.youtube.com/watch?v=VaGO3oFMJEw

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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.

Answer 6

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

Answer 7

@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.

Answer 8

thank you! I wish I could give you all a medal

Answer 9

No problem!
