What is the term for the breakdown of glucose in the absence of oxygen?

The breakdown of glucose in the absence of oxygen is termed as anaerobic respiration.

Explanation:

Anaerobic respiration or anaerobic oxidation occur in absence of oxygen molecule within the cytoplasm of cell that ultimately leads to the formation of lactate from pyruvate by the catalytic activity of lactate dehydrogenase enzyme.This reaction helps in the regeneration of NAD+.

    During  Anaerobic respiration only 2 molecules of ATP are formed by substrate level phosphorylation .

first, consult an activity series chart to determine if al is more reactive than fe. it is, so it will replace the fe. now, one can continue with the problem.

next, make sure you have a correctly balanced equation.

3feo + 2al ==> 3fe + al2o3

now, determine which reactant (feo or al) is in limiting supply.

moles feo present = 125 g x 1 mole/71.8 g = 1.74 moles

moles al present = 25.0 g x 1 mole/26.98 g = 0.927 moles

since from the balanced equation, it take 3 mol feo for every 2 mol al, al will be limiting.

you can determine this simply by dividing moles of each by their coefficient in the balanced equation. for example: 1.74/3 = 0.58 and 0.927/2 = 0.464. al is less, so it is limiting.

finally, using the stoichiometry in the balanced eq. determine mass of fe that can be produced from 0.927 moles of al.

0.927 moles al x 3 moles fe/2 moles al x 55.8 g/mole = 77.6 g

the millers tale is the answer.
