soap is an effective dropdown because it dropdown waters surface tension and allows it to dissolve nonpolar substances.

Explanation:

Identify the role of soap

Using the Surfactants knowledge point, soap acts as a surface-active agent. It reduces the cohesive forces between water molecules. Therefore, the first blank is "surfactant".

Determine the effect on surface tension

Using the Surface Tension Causes knowledge point, soap molecules disrupt hydrogen bonding at the water's surface. This disruption decreases the cohesive forces. Therefore, the second blank is "decreases".

Answer:

Use the drop-down menus to complete the sentence correctly.

Soap is an effective <blank>surfactant</blank> because it <blank>decreases</blank> water's surface tension and allows it to dissolve nonpolar substances.
