Question
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?

Answer options with 4 options
A.
Oxygen dissolves in water.

B.
Carbon is a solid at 145 ° Celsius.

C.
Hydrogen dissolves in water.

D.
Oxygen becomes a gas at negative 183 ° Celsius.

Answer 1

The best option that demonstrates how the atoms that make up glucose have different properties than the molecule glucose is:

B. Carbon is a solid at 145 ° Celsius.

This option highlights that carbon, when isolated, has different physical properties (solid state) compared to glucose, which is a solid with a melting point of 146 °C. The other options pertain to single elements dissolving in water or changing states, but they do not directly illustrate the differences in properties between the individual atoms and the compound (glucose) itself.
