Sagot :
Answer:
159.7 grams Fe2O3
Step-by-step explanation:
The balanced equation tells us that CO, not CO2, reacts with Fe2O3. The answer below assumes that CO, was intended in the phrase "react with 3.0 moles of CO2."
Fe2O3 + 3CO ---> 2Fe + 3CO2
React with 3.0 moles of CO.
The equation states we need 3 moles of CO for every one mole of Fe2O3 to have a balanced reaction. The molar mass of Fe2O3 is 159.7 grams/mole, so we'd need 159.7 grams of Fe2O3.
===============
If the statement was meant to read "produce 3.0 moles of CO2:
Produce 3.0 Moles of CO2
We would still only need one mole of Fe2O3, so the answer is trhe same as above: 159.7 grams of Fe2O3.
