1. The use of microscale techniques does not change the hazardous nature of the reagents we use. Briefly describe the hazards associated with even small amounts of each of the following: a. concentrated hydrochloric acid‚ HCl HCL may be corrosive. It can cause burns to dosy tissue and can be deadly if inhaled or swallowed. b. sodium hydroxide‚ NaOH‚ solution NaOH is a very corrosive chemical and contact with it can cause burns to body tissue and

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

compositions corresponding to industrial conditions was used. A method of sequential regression analysis was applied to determine the kinetic parameters from the temperature and conversion profiles of the bed. The experimental data could be fitted by a power-law type of reaction rate expression. The rate equation combined with a plug flow model of the bed was successfully used to predict the fixed-bed behaviour within large temperature‚ concentration and space velocity intervals. 1.

Post-Lab Report for Experiment 2: Cooperative Identification of an organic Solid October 6‚ 2013 Introduction: This experiment was focused on the cooperative identification of organic compound by its chemical properties such as: slow melting point‚ mixed melting point‚ Rf values in TLC experiment‚ IR spectrum analysis‚ and H NMR spectra. Such data can provide the the identity of functional groups and the identity of the compound itself. In this experiment
