Plesase Help! Fe2O3 + CO → Fe + CO2

If 3 moles of Fe2O3 react with 1.5 moles of CO, how many moles of each product are formed?

1 mole of Fe and 1.5 moles of CO2
0.5 mole of Fe and 1 mole of CO2
6 moles of Fe and 9 moles of CO2
3 moles of Fe and 2 moles of CO2

6 moles of Fe and 9 moles of CO2 (Third option)

Explanation:

I just took the test, and this answer is correct

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
