Term | Definition |
Heat | Energy that is transferred as a consequence of temperature differences |
Hess's Law | Enthalpy is a sate function and is therefore independent of path. |
Heterogeneous catalysts | Catalysts that are in a different phase than the reactants |
Homogeneous catalysts | Catalysts that have the same phase as at least one of the reactants |
Homogenous mixture | A mixture with a composition that is always the same no matter what part of the sample you observe |
Homonuclear diatomic | A molecule composed of two identical atoms |
Hypothesis | An educated guess that attempts to explain observations |
Ideal gas | A gas whose molecules (or atoms) are very small compared to the total volume of the gas, make elastic collisions with one another an well as the walls of the container, and have no attraction to one another |
Incomplete combustion | A reaction in which O₂ is added to a compound containing carbon and hydrogen, producing either CO or C along with H₂O |
Indicator | A substance that turns one color in the presence of acids and another color in the presence of bases |
Insoluble | Unable to dissolve |
Intermediate state | A complex formed in the process of a chemical reaction when reactants and products are interacting |
Ion | An atom that has gained or lost electrons and thus become electrically charged |
Ionic compound | A compound formed by ions |
Ionization potential | The amount of energy needed in order to take an electron away from an atom |
Isotopes | Atoms with the same number of protons but a different number of neutrons |
Isotopes enrichment | The process by which the abundance of one isotope in a element is increased. It is typically used to make the fuel for nuclear bombs. |
Joule | The metric unit for energy |
Kelvin | The absolute temperature scale: it is not possible to reach or go below 0 Kelvin |
Kinetic energy | Energy that is in motion |
Kinetic Theory of Matter | The theory that the atom or molecules which make up a substance are in constant motion, the higher the temperature, the greater their speed |
