If a substance is composed of atoms arranged in one particular way, how is this substance best classified? a. element b. compound c. mixture d.Gas The data table below represents observations made by a scientist during an investigation. Use this table to answer the questions that follow. A scientist preformed an investigation with samples listed in the data table above. She heated the 2 liquid samples until boiling. After a while, all of the liquid evaporated from Sample 1 and the container was empty. Later, all of the liquid evaporated from Sample 2 and a colorless powder remained. 2. Based on the information presented in the data table, which term best describes Sample 1? a. atom b. element c. mixture d. compound 3. Which term best describes Sample 2? a. atom b. element c. mixture d. compound
