The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down

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

What Moves the Oil and Gas Price? Why are oil prices and gas prices so dramatically increased in the last view years? Oil and gas price will maintain the current level or rise in the next years because of the world economy‚ an increased demand on oil and its production costs‚ the gas demand‚ and the investment in developing alternative energy sources. How long will the oil reserves last? It is currently estimated that the oil reserves in the United States will last for 20 to 30 years

muscles then relax allowing a decrease in the volume of the thorax. The decreased volume increases the pressure in the lungs‚ so the pulmonary pressure is now greater than the atmospheric pressure‚ thus is forced out of the lungs. Gas exchange takes place through a gas exchange surface‚ (also known as a respiratory surface) and is the process of getting oxygen by taking air into the blood‚ and the removal of carbon dioxide waste from the blood into the air. The removal of carbon dioxide from the

The Natural Gas Case In the Natural Gas case‚ a German company and a Dutch gas reseller (the plaintiffs) is suing an Austrian partnership company (the defendant) for a breach of contract. The plaintiffs negotiated and agreed to purchase 3000 metric tons of propane gas for $381 per metric ton from the defendant. Because of the two companies never conducting business with one another‚ the plaintiffs agreed to secure a letter of credit with its purchase. To secure the letter of credit with the purchase
