Briefly explain the appropriate procedures in handling liquid with a micropipette Basically‚ there are two types of technique used for handling liquid using micropipette. One of them is the forward pipetting and another one is reverse pipetting. The usage of these techniques varies with the type of liquid that will be handled. Forward pipetting normally use for pipetting the aqueous solution‚ acid and alkali‚ volatile compound and also radioactive compound. Forward pipetting has higher accuracy

the air gap space. The module are made of Perspex to resist corrosion by the NaCl solution. The feed NaCl solution flows through the right cell while the cooling water passes through one side of the condensing plate in the left cell. The permeate liquid is collected in the middle cell‚ which is placed between the feed and coolant. The condensing plate is made of stainless steel. The AGMD system is vertically installed. The permeate and feed are separated by a porous hydrophobic membrane. The effective

INTRODUCTION Archie Unleashed is an attempt to put the basic log analysis methodology for computing water saturation into a readable reference document. The beginning log analyst or petrophysicist should have little difficulty with the terms and concepts utilized in this paper‚ however‚ most terms are redefined in appendix A. The basic outline of this document closely follows a previous work written for the casual interpeter in log analysis. Archie Unleashed is meant to carry that work one step

9.1 Orbitals and Theories of Chemical Bonding 1. Which one of the statements concerning valence bond (VB) and molecular orbital (MO) bond theories is correct? a) MO theory predicts that electrons are localized between pairs of atoms. b) In VB theory‚ bonding electrons are delocalized over the molecule. c) MO theory accurately describes bonding in O2 and NO‚ VB theory does not. d) VB theory can describe molecular bonding in excited states. e) MO theory is used to accurately predict

will learn how to measure length‚ temperatures‚ volume‚ density‚ and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials: a metric ruler‚ table salt‚ small number of ice cubes‚ piece of string‚ flame source‚ rubbing alcohol‚ tap water‚ distilled water‚ paper‚ colored liquid drink‚ 100mL glass beaker‚ burner-fuel‚ burner-stand‚

Ezekiel 10/7/13 Introduction A lava lamp (or Astro lamp) is a decorative novelty item‚ invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive of pāhoehoe lava‚ hence the name. The lamps are designed in a variety of styles and colours. The underlying fluid

non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular diffusion. The initial reading and every 2 minutes subsequent reading of the liquidacetone level are determined‚ and the experiment is conducted for 10 minutes. The experiment is repeated by changing temperature to 45oC

Archimedes’ & Pascal’s Principle Purpose In this lab‚ we will prove Archimedes’ Principle by finding the density of a Metal Cylinder‚ a cork‚ and an unknown fluid by using Archimedes’ Principle. We will also use the PASCO Pascal’s Principle Lab Setup to investigate the use of fluid pressure as a hydraulic system to do work and we will find its mechanical advantage. Procedure For the first part of the lab we will be verifying case 3 as explained by professor. We
