When two different liquid chemical compounds at room temperature are mixed together, the beaker they are poured into is icy to the touch. What kind of reaction is this an example of? A. a fission reaction B. a combustion reaction C. an exothermic reaction D. an endothermic reaction
Explanation: since the reaction vessel is icy to touch, it means the system gains heat as the surroundings cool down. This is clearly an endothermic reaction.
