Balanced equation:
4 FeS₂ + 11 O₂ --> 2 Fe₂O₃ + 8 SO₂
---
Find the limiting reactant (the one that produces the least amount of product) :
(73.5 g FeS₂) * (1 mole FeS₂ / 119.975 g FeS₂) * (2 moles Fe₂O₃ / 4 moles FeS2) * (159.6882 g Fe₂O₃ / 1 mole Fe₂O₃)
= 48.9 g Fe₂O₃ …………. to 3 sig figs
(44 g O₂) * (1 mole O₂ / 31.9988 g O₂) * (2 moles Fe₂O₃ / 11 moles O₂) *
(159.6882 g Fe₂O₃ / 1 mole Fe₂O₃)
= 40 g Fe₂O₃ ………………. to 2 sig figs
O₂ is the limiting reactant and the theoretical yield is 44 g Fe₂O₃
Answer:
yes
Explanation:
since humans dig out the earth for resources o believe that fossils far every species that exists and is extinct will be found and will be pieced together
Answer:
used to complete the glicolisis process
Explanation:
A glucose molecule will generate the necessary energy to the body to compete their own metabolic processes.
At the begging of the process, the glucose change into 2 molecules of gliceraldehyde 3 - phosphate. In this first process the glucose molecule consume 2 molecules of ATP (the energetic molecule).
After this first process, the aldehyde turns into piruvate, during this process, there is produced 2 molecules of ATP, so it is producing chemical energy.
If during this process the cell need to enter into another metabolic process (pentose ways) then the gain of ATP deplets.
