Answer:
A
Explanation:
The dissolving process depends on the interaction between solute and solvent (solvation) and the breaking up of the intermolecular bond between solutes. The former is exothermic in nature, while the later is endothermic. Energy is released when solute-solvent particles interact. When this energy exceeds the energy required to break intermolecular bonds between the solute particles, dissolution is exothermic.
The mass of the water displaced by the metal is 48.42 g.
Let's consider:
- mass of the metal (mM): 15.32 g
- mass of the water (mW): ?
- mass of the empty volumetric flask (mF): 65.03 g
The mass of the volumetric flask with water and the metal is 128.77 g, that is:
The mass of the water displaced by the metal is 48.42 g.
