Question

what allows water to dissolve many substances? its varying density its high heat capacity its high surface tension its polarity and hydrogen bonding

Explanation:

Water is a polar molecule with a bent shape. The oxygen - hydrogen bonds are polar, and water molecules can form hydrogen bonds with other polar or charged substances. This polarity and hydrogen - bonding ability allow water to dissolve many substances. Varying density, high heat capacity, and high surface tension do not directly relate to water's ability to dissolve substances.

Answer:

Its polarity and hydrogen bonding
