Silane, SiH4, is the silicon analogue of methane, CH4. It is prepared industrially according to the following equations: a. If 156 mL HSiCl3 (d 1.34 g/mL) is isolated when 15.0 L HCl at 10.0 atm and 35C is used, what is the percent yield of HSiCl3? b. When 156 mL HSiCl3 is heated, what volume of SiH4 at 10.0 atm and 35C will be obtained if the percent yield of the reaction is 93.1%? 1
Wednesday, January 13, 2016 Review of Intro Chem Chapter 1 Objectives - Define/ apply/ understand the following terms • States of matter • Properties of matter and its changes • Energy - The scientific method - Measurements • Units and converse factors • Temperature scales • Density - Significant figures • How to count, perform calculation • Accuracy vs precision • Important when in the lab. Each beaker or buret or pipette has different amount of significant digits States of Matter - Solid, Liquid and Gas • Aqueous- have a solution where the solvent is water (because you can have other solvents as well) • Solute vs solvent • Physical vs Chemical properties - Phys
