How many moles of so3 are produced by 2.3 mil fes2

4.6 moles SO₃

4FeS₂ +15O₂ →2Fe₂O₃ + 8SO₃

We are required to determine the number of moles of SO₃ that are produced.

Hence;

Moles of SO₃ = 2.3 moles × 2

                      = 4.6 moles

Thus, 4.6 moles of SO₃ will be produced when 2.3 moles of FeS₂ are used.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
