Glucose is made up of hydrogen, oxygen, and carbon atoms.
What evidence shows that the atoms that make up glucose have different properties than the molecule glucose?
A. Oxygen dissolves in water.
B. Carbon is a solid at 145 deg * C
C. Hydrogen dissolves in water.
D. Oxygen becomes a gas at - 183 deg * C
The correct answer is C. Hydrogen dissolves in water.
Hydrogen atoms in glucose have different properties than the glucose molecule itself. While glucose is a solid and does not readily dissolve in water, hydrogen atoms are gaseous and can dissolve in water. This difference in solubility between the molecule and its constituent atoms demonstrates that the atoms have different properties than the molecule itself.
