What is the coefficient of Fe?
Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients. The coefficient for iron metal is C. 4.
What is the chemical equation of Fes?
FeS
Iron(II) sulfide/Formula
How do you calculate fe2o3 from FE?
Using atomic weights of Fe = 55.845(2) and O = 15.9994(3), we obtain molecular weights for Fe2O3 = 159.688 and 2(FeO) = 143.689. This gives a conversion factor of 159.688 / 143.689 = 1.1113. We can then use the expressions: Fe2O3T – FeO * 1.1113 = Fe2O3V.
