The scientist we chose for our project is John Dalton. Who is John Dalton‚ you might ask? John Dalton was an English chemist‚ physicist‚ and meteorologist. He is best known for the discovery of the modern atomic theory. The rules for the atomic theory are that all matter is made up of tiny particles‚ or atoms‚ atoms are always invisible and indestructible‚ all atoms of a given element are identical in mass and properties‚ compounds are formed by a combination of two or more different kinds of atoms

the MEA process that was run at Tarong pilot plant will be discussed based on the simulation process results were obtained from the Aspen plus V8.4. The flow rate of the flue gas of 599.9kg/hr at 103.7◦C generated from the coal-fired power station entered the pilot plant through the pre-treatment column. The flow rate of flue gas became 585.8kg/hr due to the removed of acidic components and water and its temperature was reduced to approximately 32.6◦C due to cooled process. The amount of cooled water

react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Experiment Before I began the experiment I gathered all my supplies from the given list in the lab manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper and gas delivery plastic system on the test tube and arranged the tube in the well plate.

it‚ and turned it upside down into a tub of ice-cold water‚ crushing it with pressure. The movement of gas particles was a crucial component of this experiment. After the can was placed onto the hot plate‚ as the water heated up‚ the gas particles inside of the can started to move faster due to the relationship between temperature and the average kinetic energy‚ or average motion energy‚ of the gas particles. As the temperature increased‚ so did the speed of the particles inside of the can. Particles

Two or more gases can form a solution. Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas. b. Liquid Solution- contain a liquid solvent in which gas‚ liquid‚ or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution. c. Solid Solution- is a mixture of solids spread equally throughout

WHAT IS FUMIGATION? Fumigation is the process by which a lethal chemical is released into an enclosed area to eliminate an infestation of pests. This process may be used in order to rid a home or other structure of insects such as termites or roaches‚ but it may also be used when products are being processed for export or import in order to rid the goods of exotic pests and organisms. Fumigants are a unique and particularly valuable group of pesticides that can kill insects where no other form
