General Properties of Gases

Properties of Gases

• There is a lot of “free” space in gases
• Gases can be expanded infinitely
• Gases occupy containers uniformly & completely • Gases diffuse & mix rapidly Gas properties can be modeled using math which depends on:
• V = volume of the gas (L or dm3)
• T = temperature (K)
• n = amount (mol)
• P = pressure (atm)

...between molecular structure and optical activity. This discovery laid the foundation of the science of stereochemistry, which deals with the spatial arrangement of atoms in molecules. This hypothesis was put forward in the same year by the Dutch physical chemist Jacobus Henricus van 't Hoff. Le Bel wrote Cosmologie Rationelle (Rational Cosmology) in 1929. 2. Pierre Eugène Marcellin Berthelot (25 October 1827 – 18 March 1907) was a French chemist and politician noted for the Thomsen-Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances and disproved the theory of vitalism. He is considered as one of the greatest chemists of all time. He was born in Paris, France, the son of a doctor. After doing well at school in history and philosophy, he became a scientist. 3. Yves Chauvin (born October 10, 1930) is a French chemist and Nobel Prize laureate. He is honorary research director at the Institut français du pétrole and a member of the French Academy of Science.

Photon Correlation Spectroscopy

...Photon correlation spectroscopy Photon Correlation Spectroscopy (PCS) is a technique that is used to determine the size distribution of small particles in suspension or polymers in liquid solution. It’s also known as dynamic light scattering. It can also be used to probe the behavior of complex fluids such as concentrated polymer solutions. Principle When light hits small particles, the light scatters in all directions as long as the particles are small compared to the wavelength. According to the Stokes Einstein’s theory, particle Brownian motion depending on the viscosity of the suspending fluid, temperature of the fluid, diffusion coefficients of polymeric samples, molecular weights of polymers and the size of particles suspending in the fluid. Thus, the graph of scattered light can be used to determine the diffusion of particles which correlates the particle sizes. Application PCS is used to characterize size of various particles including proteins, polymers, micelles, carbohydrates, and nanoparticles. If the system is mono-disperse, the mean effective diameter of the particles can be determined. This measurement depends on the size of the particle core, the size of surface structures, particle concentration, and the type of ions in the medium. Since PCS essentially measures fluctuations in scattered light intensity due to diffusing particles, the diffusion coefficient of the particles can be determined. PCS software of commercial instruments typically displays...

GUPTA1, A. NAOUMIDIS1 and P. NIKOLOPOULOS2 Institut fur Werkstoffe und Verfahren der Energietechnik (IWV1), Forschungszentrum Julich, D-52425 ¨ ¨ Julich, Germany and 2Chemical Engineering Department, University of Patras, GR 265 00 Patras, Greece ¨ 1 Abstract—For solid oxide fuel cells (SOFCs) operating at intermediate temperatures the adjacency of the state-of-the-art yttria-stabilized zirconia (YSZ) electrolyte with ceria-based materials to both anodic and cathodic sides is regarded as crucial for the effectiveness of the cell. Solid-state reaction, however, and interdiffusion phenomena between YSZ and ceria-based materials can cause degradation of the electrolyte. When a gadolinia-doped-ceria (GDC) layer is used to protect YSZ against interaction with Co-containing cathodes, an unfavorable solid state reaction at the YSZ–GDC interface can be efficiently suppressed when a thin ( 1 µm thick) interlayer with nominal composition of Ce0.43Zr0.43Gd0.10Y0.04O1.93 is incorporated at the interface. When ceria is to be employed at the electrolyte–anode interface to reduce polarization losses, use of a ceria–40% vol Ni cermet is recommended, since suppression of the reactivity between YSZ and ceria can also be achieved in the presence of Ni. © 2000 Acta Metallurgica Inc.

Branches of Chemistry

...Physical chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of laws and concepts of physics. * Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about thereaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. * Chemical physics is a subdiscipline of chemistry and physics that investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics. * Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (theelectrode: a metal or a semiconductor) and an ionic conductor (the electrolyte). * Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales, approximately 10–15 seconds (one femtosecond, hence the name). The steps in some reactions occur in the femtosecond timescale and sometimes in attosecond timescales,[1] and will sometimes form intermediate products. * Geochemistry is the science that uses the tools and principles...

...Certificate of Education Chemistry 5421 CHM2 Foundation Physical and Inorganic Chemistry Mark Scheme 2006 examination - June series Mark schemes are prepared by the Principal Examiner and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation meeting attended by all examiners and is the scheme which was used by them in this examination. The standardisation meeting ensures that the mark scheme covers the candidates’ responses to questions and that every examiner understands and applies it in the same correct way. As preparation for the standardisation meeting each examiner analyses a number of candidates’ scripts: alternative answers not already covered by the mark scheme are discussed at the meeting and legislated for. If, after this meeting, examiners encounter unusual answers which have not been discussed at the meeting they are required to refer these to the Principal Examiner. It must be stressed that a mark scheme is a working document, in many cases further developed and expanded on the basis of candidates’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoided; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper.

...CHEMISTRY CHEMISTRY (CLASSES XI–XII) Rationale Higher Secondary Stage is the most crucial stage of school education because at this stage specialised discipline based, content oriented courses are introduced. Students reach this stage after 10 years of general education and opt for Chemistry with a purpose of mostly for pursuing their career in basic sciences or professional courses like medicines, engineering, technology and studying courses in applied areas of science and technology at tertiary level. Therefore, at this stage, there is a need to provide learners with sufficient conceptual background of Chemistry, which will make them competent to meet the challenges of academic and professional courses after the higher secondary stage. National Curriculum Framework for School Education – 2005 recommends a disciplinary approach with appropriate rigour and depth with the care that syllabus is not heavy and at the same time it is comparable to the international level. It emphasizes a coherent focus on important ideas within the discipline that are properly sequenced to optimize learning. It recommends that theoretical component of Higher Secondary Science should emphasize on problem solving methods and the awareness of Syllabus for Secondary and Higher Secondary Levels 22 historical development of key concepts of science be judiciously integrated into content. The present exercise of syllabus development in Chemistry at Higher Secondary Stage is based on this framework...

Types of Labs

...there. Most laboratories will have several large pieces of equipment, numerous smaller pieces and several computers linked in. The storage required will vary with specialist facilities for radioactive, flammable and toxic materials. Chemistry laboratories Chemistry laboratories tend to break down into the following generic spaces: organic chemistry, inorganic chemistry, physical chemistry and analytical chemistry. Biosciences (biology) Laboratories These laboratories, sometimes also called life sciences laboratories, serve as work spaces for a host of special research interests reflecting the investigators' research direction. They are distinguished by the support space that is required for each laboratory or group of laboratories. Fume hoods, as well as biosafety cabinets and laminar flow hoods, are used in all areas of bioscience research. Storage for chemicals (solvents and acids) must be provided in accordance with applicable codes. Physical Sciences Laboratories Physical science laboratories are distinguished from other types of laboratories in a number of ways. First, there is only a small amount of built-in furniture. Second, there is abundance and a variety of electrical power. This, of course, is due to the fact that in most physical sciences research labs the floor space is occupied by an array of apparatus and instrumentation, both home-built and store bought. Almost all of this equipment requires power of varying voltage and amperage... Power and piped services...
