Carbon — pay attention to your periodic table trends
Answer: maybe mixing with an acid? They are all very similar
Explanation:
Maybe because the different acids have different atoms and molecules
Since the question says “these” I assume it was multiple choice...but anyways, intermolecular forces between some of the water molecules are breaking apart. The H2O is going from a tightly packed solid of a fixed volume to a liquid with molecules moving faster and less bonds, which can take the shape of its container. It requires energy to break a bond, so this is an endothermic process.
