What chemical properties does soap have that makes it a good cleaning agent?

Soap is an excellent cleanser because of its ability to act as an emulsifying agent. An emulsifier is capable of dispersing one liquid into another immiscible liquid. This means that while oil (which attracts dirt) doesn't naturally mix with water, soap can suspend oil/dirt in such a way that it can be removed.

A molecule of soap has a hydrophilic anionic "head" and a hydrophobic "tail" made of hydrocarbons

Explanation:

The head of the molecules is attracted and dissolves in water, while the hydrocarbon tail is attracted to dirt and grease, and repelled by water. Soap is also a surfactant — it reduces the surface tension of water.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
