[Chemistry] Chemical Reaction, limiting reactants and result stoichiometry

Click For Summary
SUMMARY

The discussion centers on determining the limiting reactant and resulting stoichiometry in the reaction between vanadium (II) oxide (VO) and iron(III) oxide (Fe2O3) based on the equation 2 VO + 3 Fe2O3 -> 6 FeO + V2O5. The calculations reveal that 609.5 grams of VO corresponds to 9.11 moles, while 832 grams of Fe2O3 corresponds to 5.21 moles. The limiting reactant is identified as Fe2O3, which dictates the amount of products formed, specifically 13.6 moles of FeO and 3.47 moles of V2O5.

PREREQUISITES

Homework Statement



609.5 grams of vanadium (II) oxide, VO, and 832 grams of iron(III) oxide, Fe2O3, react according to the equation, which substance(s) and how many grams of each would be in the tube after the reaction completes? 3 points

Homework Equations


Equation:

2 VO + 3 Fe2O3 -> 6 FeO + V2O5

3.

1 mol VO = 66.94 g
1 mol Fe2O3 = 159.70 g

\frac{609.5 g VO}{66.94 g/mol VO} = 9.11 mol VO

\frac{832 Fe_{2}O_{3}}{159.7 g/mol Fe_{2}O_{3}} = 5.21 molFe_{2}O_{3}

The Attempt at a Solution


\frac{9.11 mol VO * 3 mol Fe_{2}O_{3}}{2 mol VO} = 13.6 mol Fe_{2}O_{3}

\frac{5.21 mol Fe_{2}O_{3} * 2 mol VO}{3 mol Fe_{2}O_{3}} = 3.47 mol VOSo the limiting reactant would be Fe_{2}O_{3}, right?

I'm not quite sure where to go after this, any pointers in the right direction?

Thanks :)

Consume all the Limiting reagent to form products. Find the amount of excess reagent used with LR, find the amount of products. Balanced Stoichiometric equation helps.
