2/25 HW – Limiting Reactants and Percent Yield

1. A process by which zirconium metal can be produced from the mineral zirconium (IV) orthosilicate, ZrSiO₄, starts by reacting it with chlorine gas to form zirconium (IV) chloride, silicon dioxide, and oxygen gas. What mass of zirconium (IV) chloride can be produced if 862 g of ZrSiO₄ and 950. g of chlorine gas are available? You must first determine the limiting reactant.

2. In the production of copper from ore containing copper (II) sulfide, the ore is first roasted (burned) to change it to the oxide. What mass of CuO can be formed from the reaction of 18.7 g of CuS and 12.0 g of oxygen?
