Prelab quiz - e9 - quantification of iron started: nov 3 at 2: 35pm quiz instructions prelab quizzes must be completed and submitted no later than before your scheduled lab. a completed and submitted prelab quiz is a requirement to attend lab. the prelab quizzes replace the prelab questions. due date listed only represents the last date the quiz is available to all students; ie, last day of round robin experiments. the quizzes have 10 questions, with 5 multiple choice and 5 true false. there is no time limit on the quizzes, however after you answer a question you may not go back to that question. on question 10 be sure to "submit for grading" (entering save, does not enter the grade into the gradebook). when you enter submit for grading, be sure to enter to hit submit for grading a second time as prompted. question 32 pts the concentration of hcl used for this experiment is a. 6.0 m b. 2.0 m c.1.0 m d. 12.0 m

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.
