1 Which best defines concentration?A ratio that describes the amount of solute divided by the amount of solvent or solutionB ratio that describes the amount of solvent or solution divided by the amount of solute C ratio that describes the mass of solute divided by the mass of solvent D ratio that describes the amount of solvent in a solution

ANSWER: (A) ratio that describes the amount of solute divided by the amount of solvent or solution

2 Which contributes to the dissolution of sugar in water?A the dissociation of an ionic compound in waterB a strong pull of water molecules on an ionic compoundC the dissociation of a polar covalent compound in waterD a strong pull of water molecules on a polar covalent compound

ANSWER: (D) a strong pull of water molecules on a polar covalent compound

ratio that describes the amount of solute divided by the amount of solvent or solution

Explanation:

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.
