What change should the group make to the checklist to correct their mistake?
A
Boiling point and density should be moved to the physical property side of the list, and color and odor should be moved to the chemical property side of the list.
B
Boiling point and density should be moved to the physical property side of the list, and hardness and mass should be moved to the chemical property side of the list.
C
Dissolves in water and boiling point should be moved to the physical property side of the list, and odor and mass should be moved to the chemical property side of the list.
D
Density and boiling point should be moved to the physical property side of the list, and odor should be moved to the chemical property side of the list.
