ire is an example of ________________ reaction, because heat is _____________ the system.
a
exothermic; entering
b
endothermic; leaving
c
exothermic; leaving
d
endothermic; entering
c. exothermic; leaving
The answer to this question can be determined by understanding the concepts of exothermic and endothermic reactions.
An exothermic reaction is a reaction that releases heat energy into its surroundings, meaning heat is leaving the system. On the other hand, an endothermic reaction is a reaction that absorbs heat energy from its surroundings, so heat is entering the system.
In the given example, it states that heat is leaving the system. This means that the reaction is releasing heat into its surroundings. Therefore, the example represents an exothermic reaction.
So, the correct answer is:
a) exothermic; entering
The correct answer is:
c) exothermic; leaving
