In the lab,you mix two solutions (each originally at the same temperature)and the temperature of the resulting solution decreases.Which of the following is true?

Question

Quizplus · Accepted Answer

When the temperature of a mixture decreases, it indicates that the energy is leaving the system. This means that the system is absorbing energy from the surroundings, not releasing it. Therefore, the correct answer is (C) - the chemical reaction is absorbing energy. Option (A) is incorrect as it suggests that the chemical reaction is releasing energy. Option (B) is also incorrect as it provides a formula that is not relevant to the question. Option (D) uses the term exothermic which is not accurate to describe the scenario as the temperature is decreasing.
