Turn In
ideal gas law
ideal gas
Gases that conform to the basic principles of kinetic-molecular theory.
Molecules don’t mix well together, and form a heterogeneous mixture- exhibiting a noticeable bilayer.
Used to measure pH. Changes color depending on the pH of the solution.
inductive reasoning
Involves getting a collection of specific examples and drawing a general conclusion from them.
initial rate of reaction
The rate at the very beginning where the reactant concentration has not changed appreciably and the product concentration is negligible.
It does not dissolve, and it does not dissociate in water.
intensive properties
Physical properties that do not depend on amount. Examples include color, taste, melting point, boiling point, density, luster, and hardness.
Formed when elements either gain or lose electrons.
ion-product constant
An equilibrium constant. Kw = [H+][OH-] = 1.0 × 10-14 at 25°C
ionic bond
An electrostatic attraction between two ions that have exchanged electrons.
ionic compounds
A compound formed by ions bonded together through electrostatic forces.
ionic equation
An equation in which dissolved ionic compounds are shown as free ions.
ionic radius
The radius exhibited by an ion in an ionic crystal where the ions are packed together to a point where their outermost electronic orbitals are in contact with each other.
ionization energy
The energy required to remove an electron from a specific atom. It is measured in kJ/mol, which is an energy unit, much like calories.
Having equal numbers of electrons or the same electronic configuration.
Atoms that have the same atomic number but different mass numbers due to a change in the number of neutrons.
