4. state your observations upon addition of the hydrogen peroxide solution to the mixture at this point. write two half reactions, one for the h2o2 and one for the cobalt complex and the net redox reaction that occurs between these two reagents at this point in the synthesis showing products formed. a side reaction should have been observed at this point also, namely a strong effervescence of the solution upon the peroxide addition. was this observed? in addition to acting as an oxidizing agent the h2o2 can be catalytically decomposed by the metal ion. write a reaction for that process and identify the gas apparently released at this point from the solution.

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.

explanation:

it should be all of them because it asks if you included all of those in your answer

explanation:

the answer is c
