Question

1. water is essential for life due to its unusual bent polar structure. which of the following best describes a result of the polar nature of water molecules? a. ionic compounds dissolve easily in water. b. the volume of water decreases by nearly half when it is frozen. c. water molecules repel most other substances.

Explanation:

Polar water molecules have a partial - positive and partial - negative end. Ionic compounds are made of ions. The charged ends of water molecules are attracted to the ions in ionic compounds, allowing them to dissolve easily. Water expands when frozen, not decreases in volume. And water is a good solvent and does not repel most substances.

Answer:

a. Ionic compounds dissolve easily in water.
