Chemical Composition of Natural Gas Natural gas is a naturally occurring gas mixture‚ consisting mainly of methane. While most of the gas supplied to Union Gas is from western Canada‚ some gas is supplied from other sources‚ including the United States and Ontario producers. While the gas from these sources has a similar analysis‚ it is not entirely the same. The table below outlines the typical components of natural gas on the Union Gas system and the typical ranges for these values (allowing for

very efficient for transporting a variety of substance around the body. Ventilation: gaseous exchange is also a very important for exchanging materials. Oxygen and carbon dioxide are able to move easily between the lungs and the blood by diffusion. Gas and solute exchange surfaces in humans have been adapted to maximise their effectiveness. The larger an organism gets and the more complicated it is which makes it harder for materials to be exchanged. Gaseous exchange is the process by which oxygen

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected. Controlling

Experiment 9 Aim A. To investigate the existence of hydrogen bonds between ethanol molecules. B. To measure the strength of hydrogen bond formed between ethanol molecules C. To investigate the formation of hydrogen bonds between molecules of ethyl ethanoate and trichloromethane. D. To measure the strength of hydrogen bond formed between molecules of ethyl ethanoate and trichloromethane. Procedure A. 1. 10 cm3 of ethanol was added into an insulated 50 cm3 beaker by

How Much Gas is Produced? Julie Dang June 23‚ 2013 Purpose The Company ABC Chemical has asked our group to investigate the gas production from a number of various chemical reactions. The company would like us to measure the amount of product we get when we measure the amount of gas from two reactions. We will then compare our data to the predicted amount which will we will calculate based of the Law of conservation of Mass and Ideal Gas Laws. Methods Materials Thermometer CaCO3

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that
