kinetic theory states that matter is composed of a large number of particles that are in constant motion. what is the formula for the ideal gas law? pv=nrt Brainpower Read More 0:07 / 0:15 what is the formula for Charles' law? v1 over t1 = v2 over t2 chemical thermodynamics the study of the relationship between chemical reactions and the laws of thermodynamics. kinetic energy energy of motion system the portion of the universe being studied endothermic a reaction that absorbs heat entropy amount of disorder in a system calorimeter device that measures heat heat of vaporization the amount of heat per unit mass required to vaporize a substance at it's normal boiling point spontaneous reaction a reaction that can occur on it's own wavelength the distance between any two corresponding points on successive waves crest highpoint on a wave what is the speed of light? 3.00 x 10^8 quantum theory of light states that light is both a wave and a particle Bohr model states that the energy of the allowed orbits is quantized on certain levels uncertainty principle states that that either the momentum or the position of an atom can be measured separately but not both at the same time. bright colored lines in the spectrum of hydrogen gas are produced because of? the electrons are dropping from higher to lower energy levels electron configuration the complete arrangement of electrons in an atom Paul-exclusion principle states that no two electrons in an atom may have the same set of four quantum numbers. lewis symbol a symbol using dots to represent the outer energy level electrons group elements that are in columns valence electrons the outermost electrons halogens group 17 period elements that are in rows noble gases group 18 electronegativity the ability of chemically combined atoms to attract electrons to themselves octet rule states that atoms will tend to react chemically so as to achieve electron configuration ionic bond metal + nonmetal / transfers electrons covalent bond nonmetal + nonmetal / shares electrons covalent network substances composed of billions and trillions of atoms that are bonded together into a single unit by strong covalent bonds (ex. diamonds & carbon) double covalent bond sharing of 2 pairs or 4 electrons metallic bonds consists of mainly what type of electrons? delocalized electrons polar bond a covalent bond in which electrons are shared unequally tetrahedral 4 bonding pairs & 0 nonbonding pairs of electrons trigonal planar 3 bonding pairs & 0 nonbonding pairs of electrons trigonal pyrimidal 3 bonding pairs & 1 nonbonding pair of electrons angular 2 bonding pairs & 2 nonbonding pairs of electrons linear 2 bonding pairs & 0 nonbonding pairs of electrons hydrogen bond strongest intermolecular force London force weakest intermolecular force amorphous solids that have no ordered arrangement of the particles that compose them unit cell the simplest repeating unit in a crystal face-centered cubic packs the most atoms into the smallest amount of space what of an atom is affected by intermolecular forces? the melting and boiling point
