During a lab activity, students prepared two solutions separately at the same temperature. Later they mixed the solutions and the temperature dropped. Why?

There was no energy input during the chemical reaction.

Energy was absorbed during the chemical reaction.

Energy was released during the chemical reaction.

The temperature of the surroundings dropped.

exothermic reaction-energy was released during the chemical reaction

anonymous · Answer

so it is C

syedmohammed98 · Answer

um   it say's temperature dropped..don't u think it's endothermic?

anonymous · Answer

If the temp of the reaction dropped that means it lost energy...endothermic means it absorbed energy.

anonymous · Answer

So I would say C

Its phrased odd, most sites put it like this @SyedMohammed98 http://www.kentchemistry.com/links/Matter/EndoExo.htm

syedmohammed98 · Answer

"Endothermic reactions usually feel cold because it is taking heat away from you"
so it's saying that endo's decreased the temp that's why they usually feel cold
