Mustard Gas During World War I LOST was the original name for mustard gas‚ it was named after Lommel and Steinkopf. They were the first people who proposed this gas to the military to use as a weapon in 1916. Although mustard gas could possibly been developed as early as 1822 by a French chemist‚ Cesar-Mansuete Desperetez. Thirty-two years later Alfred Riche repeated this reaction of the sulfur dichloride and ethylene‚ but both Riche and Desperetez did not note any harsh properties. In 1860‚

CHG 3111 Unit Operation Gas-Liquid Separation Text Book: Chapter 10 Separation Processes Introduction: Many chemical and biological processes occur as a mixtures of different phases‚ gas‚ liquid and solid. To separate or remove one or more of the components from its original mixture‚ it must be contacted with another phase. The two phase pair can be gas-liquid‚ liquid-liquid or liquid-solid. When different phases are brought into contact‚ a solute or solutes can diffuse from on phase to the

Boyle’s Law - Solutions 1) If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L‚ what will the new pressure inside the piston be? P1V1 = P2V2 (1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm 2) I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18

Introduction to Gas Turbines A turbine is any kind of spinning device that uses the action of a fluid to produce work. Typical fluids are: air‚ wind‚ water‚ steam and helium. Windmills and hydroelectric dams have used turbine action for decades to turn the core of an electrical generator to produce power for both industrial and residential consumption. Simpler turbines are much older‚ with the first known appearance dating to the time of ancient Greece. In the history of energy conversion‚ however

is * Sulfur mustard is a type of chemical warfare agent. These kinds of agents are called vesicants or blistering agents‚ because they cause blistering of the skin and mucous membranes on contact. * Sulfur mustard is also known as “mustard gas or mustard agent‚” or by the military designations H‚ HD‚ and HT. * Sulfur mustard sometimes smells like garlic‚ onions‚ or mustard and sometimes has no odor. It can be a vapor (the gaseous form of a liquid)‚ an oily-textured liquid‚ or a solid

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Osmosis and diffusion are sometimes mixed up without much thought‚ but they are very different in many ways. Osmosis is a defined as the movement of water through a semipermeable membrane (). The membrane is fully permeable for the small water molecules‚ but is selectively permeable to any substance that is lager that a normal water molecule. One example might be a glucose and water mixture‚ when the solute is put into one side of a U-shaped tube that has a semipermeable membrane between the solvent

Oil And Gas: How Both Affect The Economy The economy is affected by many factors that determine if it is strong or weak. These factors have to do with buyers consuming goods and services and at what rate they do this. Do the goods and services that are consumed by people created wealth‚ jobs and a better overall economy for a country. Throughout history some economies have evolved faster and stronger than others.
