Chromium(III) oxide (Cr203) reacts with silicon (Si) as indicated by the balanced equation below:
2Cr2O3(s) + 3Si(s) — 4Cr(s) + 3SiO2 (s)
Determine the mass of SiO2 (60.08 g mol-2) when 80.00 g of Cr2O3 (152.0 g mol-?) reacts with 30.00 g of Si.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
