Explanation:
This student is wrong.
Chemical bonds are forces that hold atoms together to form a molecule or compound. These interactions are inside the molecule. Example
Ionic bond: NaCl (sodium and chlorine).
Intermolecular forces are weaker than chemical bonds and they are forces between atoms or molecules. These interactions are among different molecules.
Example
Two molecules of water interact forming hydrogen bridges.

Explanation:
Marble is also known as calcium carbonate and its chemical formula is
.
When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.
The reaction is as follows.

Whereas vinegar being a weak acid will not react with glass, copper and steel.
