The theoretical yield of iron metal : 16.418 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2 Fe₂O₃ + 3 C ⇒ 4 Fe + 3 CO₂
mol Fe₂O₃ (MW=159,69 g/mol) :
mol Fe₂O₃ : mol Fe = 2 : 4
mol Fe :
mass Fe(the theoretical yield) :
<span>The third equivalence point is not observed in the titration curve of phosphoric acid because the specific point is concealed due to the rapid ionization of water which in turn forms an hydroxide ion and a molecule called hydronium molecule. The pH value changes more at the first and second points.</span>
