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 + 2 Al -> 2 Cr + Al2O3
2 CrO3 + 3 Si -> 4 Cr + 3 SiO2
1. Calculate the number of grams of aluminum required to prepare 89.00 g of chromium metal by the first reaction.
2. Calculate the number of grams of silicon required to prepare 89.00 g of chromium metal by the second reaction.
