Sodium carbonate (na2co3) and potassium carbonate (k2co3) react with water to form an alkaline solution that has detergent properties. these compounds are present in:

The ashes of plants  

Explanation:

Sodium carbonate is found in large natural deposits. It is also present in the ashes of sea plants.

Potassium carbonate is the main component of potash, which includes various mined potassium salts. It is also present in the ashes of land plants.

Neither compound has detergent properties.

Rather, the carbonate ion acts as a water softener. It removes calcium and magnesium ions that interfere with the actual detergents.

Also, the solutions are strongly basic. The hydroxide ions react with the fats and oils that stain clothes and convert them to soluble compounds that can be washed away.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
