Question

A sample of 13.0 g of Fe2O3 reacts with 17.0 g CO to yield

a) FeCO₃
b) Fe₃O₄
c) Fe₂(CO₃)₃
d) Fe + CO₂

Answer 1

To find the mass of CO required to react with 25.13 g of Fe₂O₃, use the balanced chemical equation and stoichiometry. Calculate the molar mass of Fe₂O₃ and CO, convert the mass of Fe₂O₃ to moles, use stoichiometry to find moles of CO, and convert moles of CO to grams using molar mass.

Step-by-step explanation:

To find the mass of CO required to react with 25.13 g of Fe₂O₃, we need to use the balanced equation Fe₂O₃ + 3CO → 2Fe + 3CO₂. First, calculate the molar mass of Fe₂O₃ and CO. Then, use the molar mass ratios to find the moles of Fe₂O₃. Finally, use the stoichiometry of the balanced equation to find the moles of CO and convert it to grams.

1. Calculate the molar mass of Fe₂O₃: (2 x atomic mass of Fe) + (3 x atomic mass of O)
2. Calculate the molar mass of CO: (atomic mass of C) + (atomic mass of O)
3. Convert the mass of Fe₂O₃ to moles using its molar mass and the given mass: (mass of Fe₂O₃) / (molar mass of Fe₂O₃)
4. Use the stoichiometry of the balanced equation to find the moles of CO: (moles of Fe₂O₃) x (moles of CO / moles of Fe₂O₃)
5. Convert the moles of CO to grams using its molar mass: (moles of CO) x (molar mass of CO)

Follow these steps to find the mass of CO required to react with 25.13 g of Fe₂O₃.
