Question

How do you if a reaction is exthermic

Answer 1

Answer:

To know if a reaction/experiment is exothermic or endothermic depends on the temperatures of the two liquids you are trying to mix. First before mixing your liquids take the temperature of both of them and write it down. then mix both liquids together to get your reaction and take the temperature of both mixed together. write it down. Did the temperature of your liquids increase or decrease? this question will determine weather the reaction was endothermic or exothermic. Endothermic meaning the temperature got cooler and Exothermic meaning the temperature got hotter/warmer

EX. | starting temperature- 72 F | ending temperature- 82 F | Exothermic

EX 2. | starting temperature- 72 F | ending temperature- 69 F | Endothermic
