Mrs. Rosales performed a demonstration of a chemical reaction for her science students. In a well-ventilated room, she added a sulfuric acid solution to a beaker containing granulated sugar. The mixture immediately became very hot and released water vapor into the air. The sugar appeared to burn and was transformed into a rapidly growing column of solid black material. The experiment also produced a foul-smelling odor. Which observation about the demonstration does not provide evidence of a chemical reaction? A. The mixture immediately became very hot B. Water vapor was released into the air. C. The mixture released a foul-smelling odor. D. The sugar was transformed into a solid black material
