Answer:
Option D. For every mole of iron oxide consumed, two moles of iron are produced.
Explanation:
The balanced equation for the reaction is given below:
Fe2O3 + 3CO —> 2Fe + 3CO2
From the balanced equation above,
1 mole of iron oxide, Fe2O3 reacted with 3 moles of carbon monoxide, CO to produce 2 moles of iron, Fe and 3 moles of carbon dioxide, CO2.
Thus, with a careful observation of the equation, we can conclude that for every 1 mole of iron oxide, Fe2O3 consumed, 2 moles of iron, Fe are produced.
