Using hydrogen (H 2 ) to reduce magnetite (Fe 3 O 4 ) to iron (Fe) is considered to be "greener" than using carbon monoxide (CO) because

Water (H2O), the by-product of reducing magnetite (Fe3O4) with hydrogen (H2), contributes significantly less to climate change than carbon dioxide (CO2), which is the by-product of using carbon monoxide (CO) for the reduction process.

Question 76

Multiple Choice

Using hydrogen (H₂) to reduce magnetite (Fe₃O₄) to iron (Fe) is considered to be "greener" than using carbon monoxide (CO) because

A) there are more molecules of the CO₂ by-products produced than molecules of the water by-product.
B) water contributes less to climate change than carbon dioxide does.
C) using hydrogen uses much less energy than using carbon monoxide does.
D) the iron produced by using hydrogen can be replaced by aluminum more easily.
