What is the change in temperature if a solution, initially at 45.2 °C, dropped to 35.9 °C after a reaction occurred?

A. -9.3 °C
B. 9 °C
C. 9.3
D. 9.3 °C

Answer :

Final answer:

The change in temperature is -9.3 °C.


Explanation:

The change in temperature is calculated by subtracting the initial temperature from the final temperature. In this case, the initial temperature is 45.2 °C and the final temperature is 35.9 °C. So, the change in temperature is 45.2 °C - 35.9 °C = -9.3 °C. Therefore, the change in temperature is -9.3 °C.
