Catalyst by Laurie Halse Anderson‚ there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone she can. A solid

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

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.

(Homogeneous‚ Heterogeneous‚ Mixture‚ Pure Substance)? HOMOGENEOUS Matter that is made up of the same or alike particles Can’t see what makes it up Looks uniform HETEROGENEOUS Matter that is made up of different types of particles Can see what makes it up Mixture A material made up of two or more substances that can be easily separated

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

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

of Gases Purpose: The purpose of this experiment was to understand the gases; Hydrogen‚ Oxygen‚ and Carbon Dioxide. The experiment helped me understand the properties of these gases‚ specifically their physical and chemical properties.

16 Characteristics of a Gas Page 17 Pictures of Gases Page 18 Q & A Page 19 Bibliography Page 20 Kinetic Theory of Molecules The kinetic theory of molecules describes the behavior of matter in terms of particles in motion. This theory makes these assumptions: 1. Gases are made up of particles with no defined volume but with a defined mass. In other words their volume is miniscule compared to the distance between themselves and other molecules. 2. Gas particles undergo no intermolecular
