ATI TEAS – Chemistry 2022 (Answered) physical property quality or condition of a substance that can be observed or measured without changing the substance's composition Anion ion with a net negative charge Osmosis the diffusion of water and the movement of molecules from an area of high concentration to an area of lower concentration Concentration amount of solute in a given volume of solution neutralization reaction reaction that happens when an acid and a base react with each other to form water and salt Ion atom with a net electric charge what completely ionizes in solution? strong acids Plasma particles have so much energy that the electrons separate from their nuclei decomposition reactions have only one reactant (AB) that breaks apart into two or more products (A and B) Diffusion Tendency of molecules and ions to move toward areas of lower concentrations until the concentration is uniform throughout the room (that is, it reaches equilibrium) Gases more energy than solids or liquids and the cohesive forces in a gas are very weak because the particles move very quickly what is the rate of a reaction? speeed at which reactant. is consu,ed or product is formed atomic number equal to the number of protons in a single atom of that element and is how an element is identified what determines the mole ratio in a chemical equation? coefficient ionic compounds formed when electrons are transferreed from a metal (which loses one or more electrons) to a nonmetal (which gains one or more electrons) Electronegativity tendency of an atom to attract shared electrons in a covalent bond mole SI unit for measuring the amount of a substance Molarity number of moles of a substance in one liter of solution
