Chromium metal can be produced from the high-temperature reaction of Cr2O3 (chromium(III) oxide) with silicon or aluminum by each of the following reactions.
Cr2O3(s) + 2 Al(l) â 2 Cr(l) + Al2O3(s)
or
2 Cr2O3(s) + 3 Si(l) â 4 Cr(l) + 3 SiO2(s)
A) Calculate the number of grams of aluminum required to prepare 330. g of chromium metal by the first reaction.
B)Calculate the number of grams of silicon required to prepare 330. g of chromium metal by the second reaction
