4fe + 3o2 - 2fe2o3 when iron rusts in air, iron (iii) oxide is produced. how many moles of oxygen react with 2.4 moles of iron in the rusting process?

moles of oxygen (O₂) = 1.8 mole

Explanation:

Data Given:

moles of Fe (iron) = 2.4 moles

moles of Oxygen (O₂) = ?

Reaction Given

              4Fe + 3O₂ >  2Fe₂O₃

Solution:

To solve this problem we have to look at the reaction

Reaction Given

                    4Fe    +     3O₂ > 2Fe₂O₃

                   4 mol        3 mol

So if we look at the reaction; 4 mole of iron (Fe) react with 3 moles of oxygen (O₂) in a rusting reaction, then how many moles of oxygen (O₂) will react with 2.4 moles of iron (Fe)

For this apply unity formula

                     4 mole of iron (Fe) ≅ 3 moles of oxygen (O₂)

                    2.4 mole of iron (Fe) ≅ X moles of oxygen (O₂)

By Doing cross multiplication

                  moles of oxygen (O₂) = 3 moles x 2.4 moles / 4 mole

                  moles of oxygen (O₂) = 1.8 mol

2.4 mole of iron (Fe) will react with 1.8 moles of oxygen (O₂)

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
