Molar Volume of a Gas Objective: The objective is to determine the volume‚ of one mole of hydrogen gas at STP using experimental data‚ known mathematical relationships‚ and a balanced chemical equation. Theory: The goal of this lab is to find the volume of one mole of hydrogen at STP. The experimenters will be working with hydrochloric acid and magnesium to find the objective. The acid in this lab will react to the magnesium and cause the water in the eudiometer to rise because of the reaction

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

1) Explain why alveolar gas has a different composition from air. Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary

What is the temperature at the end of the process in (a)? (d) What is the pressure at the end of process in (b)? (e) Show both processes in the p-V plane. Problem 2: The temperature of an ideal gas at an initial pressure p1 and volume V1 is increased at constant volume until the pressure is doubled. The gas is then expanded isothermally until the pressure drops to its original value‚ where it is compressed at constant pressure until the volume returns to its initial value. (a) Sketch these processes

Gas Price Elasticity The Energy Information Administration of the Department of Energy began tracking weekly gasoline prices in 1990 by means of a survey of 800 service stations around the country. The average retail price for unleaded gasoline posted its fourth record high during the week of June 12‚ 2000‚ increasing 5 cents a gallon to an average of $1.681. The price at the pump is higher than the same period last year by 56 cents and has risen 16.2 cents over the past month (Anonymous‚ 2000)

Breakdown of the asset. While gas ovens can differ from model to model‚ they operate on similar principles. First lets explain how a typical gas oven operates and which problems may occur. A gas oven ignition system consists of three basic components; the oven controls‚ the igniter and the oven safety valve. In newer models the igniter will be a glow igniter‚ or in ovens that are a few years old‚ an electrical igniter. Old ovens may work with a pilot light igniter. In this breakdown we will
