what is gaas chemistry

Hydrogen is the most common naturally-occurring gas in the universe. However, the resulting particles can be nonstoichiometric due to preferential vaporization of volatile arsenic from a gallium arsenide source. Here you can browse chemistry videos, articles, and exercises by topic. It studies the composition, structure, properties and change of matter. Many reactions produce gases which can help identify the mechanisms and products involved. Chemistry Q&A Library At room temperature (i.e., 300 K), a semiconductor made of gallium arsenide (GaAs) has an intrinsic electron concentration (ni) of 1.8×10^6 cm^-3 , an electron mobility (μe) of 8500 cm^2 V^1 s^-1 , and a hole mobility (μh) of 400 cm^2 V^-1 s^-1 . She has taught science courses at the high school, college, and graduate levels. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Gases have also been used as chemical warfare agents. Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Online chemistry calculators, Periodic Table of the Elements, Ideal Gas Law, Boyles Law,Charles Law,Gay-Lussac's Law, Combined Gas Law. They and a newer agent, VX, … It is also soluble in alcohol. The ideal gas law fails when the pressure of the gas is very high or the temperature is very low. A more convient unit is the torr. American Chemical Society: Chemistry for Life. Liquefied petroleum gas, any of several liquid mixtures of the volatile hydrocarbons propene, propane, butene, and butane. A solution for which the gas phase exhibits thermodynamic … Gases behave most ideally at high temperatures and low pressures. The individual gas particles do not exert any forces on each other. Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). Gases: Oxygen and nitrogen are naturally-occurring gases. In fact, it's common for regions of a gas to contain random, transient charged regions because of van der Waals forces. 101,325 pascals equals 1 atm. Under ordinary conditions, the gas state is between the liquid and plasma states. All elements in Group VIII are gases. Understanding basic chemistry concepts is important for almost every profession. A torr is the same unit as the mmHg (millimeter of mercury). If a chemical … From a physical standpoint, the gas constant is a proportionality constant that related the energy scale to the temperature scale for a mole of particles at a given temperature. Natural gas (also called fossil gas; sometimes just gas), is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. Chemical reactions are an integral part of technology, of culture, and indeed of life itself.Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years. (b) Identify how many valence electrons each atom has. A soluteis any substance which can be either solid or liquid or gas dissolved in a solvent. A gas is defined as a state of matter consisting of particles that have neither a defined volume nor defined shape. Test what you've learned. It is normally used as a standard unit of pressure. The model makes four basic assumptions: The average kinetic energy of a gas is expressed by the formula:KEave = 3RT/2whereKEave = average kinetic energy R = ideal gas constantT = absolute temperatureThe average velocity or root mean square velocity of individual gas particles can be found using the formulavrms = [3RT/M]1/2wherevrms = average or root mean square velocityR = ideal gas constantT = absolute temperatureM = molar mass, The density of an ideal gas can be calculated using the formulaρ = PM/RTwhereρ = densityP = pressureM = molar massR = ideal gas constantT = absolute temperature, Graham's law atates the rate of diffusion or effusion for a gas is inversely proportional to the square root of the molar mass of the gas.r(M)1/2 = constantwherer = rate of diffusion or effusionM = molar massThe rates of two gases can be compared to each other using the formular1/r2 = (M2)1/2/(M1)1/2.
