How many moles of C6H12O2 are needed to get 12 moles of CO2

2 moles of C6H12O2

Explanation:

First, we'll begin by writing a balanced equation for the reaction showing how CO2 is produce from C6H12O2.

This is illustrated below:

C6H12O2 + 8O2 —> 6CO2 + 6H2O

From the balanced equation above,

1 mole of C6H12O2 produced 6 moles of CO2.

Therefore, Xmol of C6H12O2 will produce 12 moles of CO2 i.e

Xmol of C6H12O2 = 12/6 = 2 moles

Therefore, 2 moles of C6H12O2 are needed to produce 12 moles of CO2

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.
