Extracted text: QI. BHs can be made by using Lithium hydride LiH. 6LIH + 2BCI, B;H, + 6LICI If you mix 624 g of Lill with 2115 g of BCs, you recover 168 g of Bls. Determine: a) The percent of excess reactant. b) The fractional degree of completion of the reaction. c) The yield of LICI hased on BC; charged (in g/g).
