Asolution is a homogeneous mixture of one or more solutes dissolved in a solvent. a specific volume of solvent is only able to dissolve a limited amount of solute. as long as the solvent is able to dissolve more solute, the solution remains unsaturated. when the solvent can no longer dissolve additional solute, the solution is saturated. at this point, any additional solute will fall to the bottom of the container. the amount of solute that can be dissolved in a given amount of solvent at a specific temperature and pressure is defined as the solubility of the solute. consider the solubility curves of several salts in water. based on the information here, if 220 grams of the salt kbr are added to 100 ml of water at 100oc, we would label that solution as a) insoluble b) saturated c) supersaturated d) unsaturated

The solution is saturated.

Explanation:

Let´s consider the solubility curve for KBr, which represents the maximum amount of KBr that can be dissolved in 100 g of water at a certain temperature. The solubility of KBr at 100°C is approximately 105 g of KBr every 100 g of water.

The density of water is 1 g/mL. So, 100 g = 100 mL

If we add 220 g of KBr to 100 mL of water, only 105 g of KBr will dissolve and the rest (220 g - 105 g = 115 g) will precipitate. Since the solution has dissolved the maximum amount of solute possible, it is saturated.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
