Vanessa Gale Formal Lab: Evaluation of the Gas Law Constant Dr. Monzyk Due 06/25/2012 Purpose: The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT‚ where R represents the gas law constant. To determine R‚ we must find the other parameters‚ P‚ V‚ n and T through the experiment. Equipment and Materials: Large beaker Ring stand Clamp Copper wire 100 mL eudiometer tube Magnesium (Mg) ribbon M6 H2SO4 (Sulfuric Acid) Wash bottle

macromolecular or metallic. Introduction Chemical substances could be named ionic‚ molecular or metallic substance‚ based on the kind of bond present in it. Solid ionic compound is composed of ions‚ which are held together by large electrostatic forces. Bonding in molecular substance is caused by the sharing of electrons by atoms. When the stable aggregates resulting from covalent bonding contain relatively small numbers of atoms‚ they are called molecules‚ if aggregates are very large and include essentially

and fluorine all have lone pairs) forming a hydrogen bond‚ which is stronger than van der Waal’s or dipole-dipole‚ but weaker than covalent bonding. The effect of hydrogen bonding on intermolecular forces can be demonstrated very well by studying the boiling points of the group 6 hydrides b.p. comparison of main group hydrides Order of priority Hydrogen bonding strongest Dipole -dipole interactions Van der Waals forces Hydrogen bonds result from hydrogen bonded as described above.

Begin your study of biology this year by reading Chapter 1. It will serve as a reminder about biological concepts that you may have learned in an earlier course and give you an overview of what you will study this year. As you read each chapter‚ take note of the headings for each section‚ as these will clue you in to the big idea you should grasp from reading that section. One good strategy is actually to read through the review at the end of the chapter before diving into the material. Type the

March 16‚ 2012 Part One: Vanilla Bonds Abstract Understanding how to properly value a vanilla bond is essential for finance (ctuonline.edu). In theory‚ the present value relationship determines the value of a bond‚ but in practice the actual price is (typically) determined by suggestions from other‚ more liquid mechanisms. The purpose of this work will be to research bonds offered by Safeway (SWY)‚ analyze them‚ and then decide in what situation these bonds would be beneficial for the investor

WHY I WANT TO EXECUTE A TRAINING BOND In the first place we should understand the concept of a training bond‚ it is supposed to be an avenue for an employer to training employees under conditions where they pay a stipend whilst increasing their knowledge and skill of the job. The main reason for any training bond is that it stops the practice where the current employer pays for the training‚ and then as soon as you gain the qualification you jump to another better job with it‚ so the current one
