Lab Report

I. Experiment 6: hold in and trim Reagents Date Performed: 25 September 2012 Date Submitted: 02 October 2012 No Partner II. Purpose: The get of this try out is to induce the limiting reagent. The limiting reagent results when non enough of the reactants atomic number 18 present in the exact amounts calculated. The concept of stoichiometry is ingestiond to find the reactants and products. The flow, a substantial product, lead be calculated. One result learn the use of tools, such as a centrifuge and desiccator. The centrifuge will be used to separate the precipitate from the solution. This lab practices stoichiometry, and explains how the fundamental interaction of reactants can produce a product. III. turn: Dillon, Stephanie. Limiting and Excess Reagents. Laboratory Manual.
