They have the same mass
Explanation:
The two blocks have the same mass. Mass is the quantity of matter contained in a substance. Therefore, the two bodies have the same mass.
The weight is a measure of mass and gravity. The gravity on earth differs from that on the moon. Therefore, the two bodies have different weights.
Their volume is also different since one body is larger than the other. Therefore, density which is the mass per unit volume will also differ.
A chemical reaction is a reaction that changes the molecular structure and is normally irreversible.
