                                Water, with the chemical formula H₂O, constitutes over 70% of the Earth's surface and is essential for all known life. But is H₂O a micromolecule? In scientific terms, a micromolecule is a small molecule with a low molecular weight, in stark contrast to the large, complex structures of macromolecules.
