I need help asap :( Its worth 60 points 20 grams of hydrogen reacted with oxygen to form 36 grams of H20 (water). How many grams of oxygen were used up in this reaction?

Mass of oxygen react = 32 g    

Explanation:

Given data:

Mass of hydrogen = 20 g

Mass of oxygen = ?

Mass of water formed = 36 g

Solution:

Chemical equation:

2H₂ + O₂     →      2H₂O

Number of moles of water formed:

Number of moles = mass/molar mass

Number of moles = 36 g/ 18 g/mol

Number of moles = 2 mol

No we will compare the moles of water with oxygen.

               H₂O          :             O₂

                 2            :              1

when two moles of water formed one mole of oxygen react.

Mass of oxygen react:

Mass = number of moles × molar mass

Mass = 1 mol × 32 g/mol

Mass = 32 g    

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.
