will perform a quantitative analysis of a two-step reaction. Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation‚ and other stoichiometry relationships‚ you will calculate a theoretical yield of CuO‚ and your actual yield. You then will calculate a percent yield. Copper(II) sulfate pentahydrate will be dissolved in water and reacted using a double replacement reaction with sodium hydroxide. The addition of hydroxide

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

However‚ L1 and L2 capsid proteins‚ alpha-6 integrin cellular receptors and heparan sulfate proteoglycans/heparin sulfate play a major role in the binding process.19 After binding‚ through endocytosis the virus enters basal epithelial cells‚ and endosome/lysosome cause capsid disassembly. Next‚ the L2 protein facilitates transfer of the viral genome to
