Question

which property of water is likely the most significant in water’s role as a universal solvent?
o water molecules show cohesion and adhesion.
o water molecules do not contain carbon.
o the electrons in water are shared unequally, creating a slight charge.
o water contains two hydrogen atoms for each oxygen atom.

Explanation:

Water is a polar molecule due to unequal electron - sharing between hydrogen and oxygen atoms, creating a slight charge (dipole). This polarity allows water to interact with and dissolve many substances, making it a universal solvent. Cohesion and adhesion are related to water - water and water - surface interactions, not its solvent ability. The lack of carbon and the ratio of hydrogen to oxygen atoms are not the key factors for its solvent property.

Answer:

The electrons in water are shared unequally, creating a slight charge.
