In a chemical change energy can be ___? A. Created but not destroyed
B. Either created or destroyed
C. Destroyed but not created
D. Neither created nor destroyed

chemical change energy can neither be created nor destroyed.

Explanation:

the rule of law of conversion states that energy can only be converted from said energy to another. it cannot be created and destroyed.

D. Neither created nor destroyed

Explanation:

The law of conservation of energy states that energy is neither created nor destroyed.

  B. Solution

Explanation:  According to the question statement, Susan wrote in her notebook that it was a blue liquid. Therefore, from a chemistry point of view, it was a solution and not a heterogeneous mixture. Then, the solvent was evaporated after leaving the solution for 72 hours at the windowsill. The solute (blue color most likely) however was not able to evaporate with solvent and left behind.

Example: if you leave the KMnO4+water solution for a few days, water will evaporate thus leaving behind purple crystals of KMnO4.
