select the correct answer. in an experiment, lydia added 50 grams of sugar to 200 milliliters of water. she stirred the mixture, and the sugar eventually dissolved into the water and couldnt be seen. the volume of the solution increased, but there was no noticeable change in color, odor, or temperature. which statement best describes what happened in lydias experiment? a. a physical change took place during this experiment. b. a chemical change took place during this experiment. c. a compound was formed during this experiment. d. a heterogeneous mixture was formed during this experiment.

Answer

Brief Explanations:

A physical change involves a change in physical properties like state (solid - liquid), shape, or volume without changing the chemical composition. When sugar dissolves in water, it is just dispersed in the water molecules and can be retrieved by evaporating the water. There is no new chemical substance formed, no color, odor, or temperature change indicating a chemical reaction. A compound is formed through a chemical reaction, and a heterogeneous mixture has visibly distinct parts, which is not the case here as the sugar - water solution is uniform.

Answer:

A. A physical change took place during this experiment.
