of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume of a gas sample is proportional to its absolute temperature at constant pressure. Thus V ∝ T abs . In addition‚ Boyle’s Law states

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

The purpose of this lab was to learn about Newton’s laws of motion by completing an experiment‚ to see how the forces act on objects. The independent variable of this experiment is the type and amount of materials used for the interior of the vehicle (out of the material list) and how they were used. The dependent variable is how and if the interior of the vehicle protected the egg from getting cracked. The controlled variables of this experiment were the height that the vehicle was dropped from

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

Abstract: The objective of this experiment is to use Gas Chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and to find the 2 carvone’s optical activity as well as percent carvone in spearment and caraway oil. It was found that S-carvone had an optical activity of 0.0047 and R-carvone had an optical activity of 0.516 and that spearment oil is 59% carvone and caraway oil is 100% carvone. Backround: Gas Chromatography separates organic samples much in

Silver Watkins Mrs. Williams 10th Lit/Comp 29 April 2013 Euthanasia in America Murder or Justice‚ who knows? What is the exact purpose of life? Who is it that decides our fate‚ stating/deciding whether or not it’s worth being sustained? Euthanasia is a very controversial topic that is constantly being debated by many politicians. Some of these politicians have formed groups opposing the legalization of euthanasia. These politicians’ main argument is over the immorality of it‚ but still

Blood Gas Analysis at the Core Laboratory at University Hospital‚ London‚ Ontario. Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates‚ keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning

: As you can see that the greater the amount of pennies were added at the top of the cup‚ the shorter the distance of the cup moved and it included all of the three Newton’s laws. My hypothesis actually turned out to be accurate. It’s really fascinating that how only 1 experiment can prove all of Newton’s three laws of motion just like that. When the marble was getting released from the ramp I observed it hitting the cup and surprisingly the cup didn’t fall off or changed directions it went in
