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+2Al-->2Cr+Al2O3

2Cr2O3+3Si-->4Cr+3SiO2

1) Calculate the number of grams of aluminum required to prepare 87 g of chromium metal by the first reaction.

2) Calculate the number of grams of silicon required to prepare 87 g of chromium metal by the second reaction.
