Two aqueous solutions are both at room temperature and are then mixed in a coffee cup calorimeter. The reaction causes the temperature of the resulting solution to fall below room temperature. Which of the following statements is true? A. The products have a lower potential energy than the reactants.
B. This type of experiment will provide data to calculate AErxn.
C. The reaction is exothermic.
D. Energy is leaving the system during reaction.
E. None of these statements are true.

the correct option is that C. The reaction is exothermic.

Explanation:

When the temperature decreases, and that the final temperature is lower than the initial, it indicates that less calories were perceived in the calorimeter, therefore said reaction releases heat to the external environment, thus being an exothermic reaction.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
