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
