Aluminum oxide (Al2O3) and iron (Fe) react according to the following
balanced equation:
4Al2O3 + 9Fe - 3Fe304 + 8A|
If there are 10.2 grams of Al2O3 and 11.2 grams of Fe, which statement
identifies the limiting reagent in this reaction and best supports that claim?
A. Fe is the limiting reagent, because the reaction requires nearly
twice the mass of Fe as of Al2O3.
B. Al2O3 is the limiting reagent, because there are only 0.1 moles of
Al2O3 and twice as many moles of F
C. Fe is the limiting reagent, because 9 moles of Fe are required for
every 4 moles of Al2O3.
D. Al2O3 is the limiting reagent, because there are fewer grams of it
present.

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
