    Amanda Tran Date of lab: 04/25/05 Date submitted: 05/09/05 Chem 2130-3 Experiment 3: Synthesis of Co(acac-NO2)3 Introduction In this lab‚ Co(acac·NO2)3 is synthesized using the Co(acac)3 complex produced in Experiment 2. The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3‚ Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product

    Chemistry 2202 Review Final Exam Chapter 2: The Mole 1. Isotope – atoms of an element that have the same number of protons but different numbers of neutrons. Ex. The three forms of oxygen are called oxygen-16‚ oxygen-17‚ and oxygen-18. They all have 8 electrons and are written as 16/8 O (8 protons + 8 neutrons)‚ 17/8 O (8 protons + 9 neutrons)‚ and 18/8 O (8 protons + 10 neutrons). 2. 3. Mass Number – the sum of the protons and neutrons in the nucleus of one atom of a particular

The amount of product produced from a given amount of reactants based on the balanced chemical equation is referred to as the theoretical yield. The theoretical yield is based on the stoichiometry of the reaction and ideal conditions in which starting material is consumed completely‚ undesired side reactions do not occur‚ and there are no losses in the work-up procedure.

    theoretical yield from a reaction with the actual yield. % Yield = Actual yield x100 Theoretical Yield Actual Yield = Mass of product produced through experimentation Theoretical Yield = Mass of product predicted to be produced using stoichiometry A theoretical yield close to 100% is very good. Above 100% means that your product is more massive than it should be. Maybe there is something else there? Below 100% might mean that you are not producing enough product. Some of it is being
