________ Page 1 Name ______________________ Evaluation 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

thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power‚ and when pure hydrogen is used‚ the only emission from the tailpipe

Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

CK-101 Lab 03 – Lab Report Name: Will Stransky Experiment 3: Properties of Gases Questions within procedures: 1. Hydrogen G. When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused

Chemistry Catalyst Report Aim I am trying to investigate the effect of the mass of magnesium dioxide used on the speed of the reaction of 2H2O2(aq) 2H2O(l) + O2(g). I hypothesize that the speed of the reaction is proportional to the rate of decomposition. Independent Variable The mass of MnO2 used Dependent Variable The rate of decomposition through the amount of mass lost Controlled Variables Environment of the experiment Stay in the same place to carry out the experiment and finish the

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

Gas Law Problems Boyles Law 1. A gas occupies 12.3 litres at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg? 2. If a gas at 25.0 °C occupies 3.60 litres at a pressure of 1.00 atm‚ what will be its volume at a pressure of 2.50 atm? 3. To what pressure must a gas be compressed in order to get into a 3.00 cubic foot tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure? 4. A gas occupies 1.56 L at 1.00 atm. What will be the volume
