30/08/2010 08:39:00 Chem. 102 Chapter 4 Stoichiometery: study of different relationships between reactants and products in a chemical reaction In the production of acetic acid, oxygen is bubbled into acetaldehyde under pressure @ 60C. 2CH3CHO+O2 2CH3CO2H In a test of the reaction 20.0g CH3CHO and 10.0g O2 were placed in a reaction vessel. How many grams of acetic acid can be produced? (pg 2) Percent Yield: actual yield/theoretical yield *100 Concentrations of solutions: Molarity (M) moles of solute/liter of sol’n Molality (m) moles of solute/kg of solvent 2.0M sol’n of NaOH 2 moles of NaOH per L of sol’n -Determine the molatiry and molality of a sol’n 25.0g NaCl into 700g of water and give a total sol’n volume of 780 ml. (pg 3) M1V1=M2V2 If you start with 50.0 ml of a .060 M sol’n of NaBr what volume of .0500M Cl2 is needed for a complete rxn: 2Br+Cl2 2Cl-+Br2 Types of Reactions:
