Full solutions for Modern Chemistry: Student Edition 2012 | 1st Edition
A type of radioactive decay in which an atomic nucleus emits an alpha particle and thereby transforms (or “decays”) into an atom with a mass number 4 less and atomic number 2 less. (Section 21.1)
Charles’ and Gay-Lussac’s law.
See Charles’ law.
Processes in which one or more substances are converted into other substances; also called chemical reactions. (Section 1.3)
A naturally occurring solid containing hydrocarbons of high molecular weight, as well as compounds containing sulfur, oxygen, and nitrogen. (Section 5.8)
A reaction in which two or more substances combine to form a single product. (4.4)
The angle created by two intersecting planes.
The process of separating compounds on the basis of their electric charge
A form of magnetism in which unpaired electron spins align parallel to one another. (Section 23.1)
In radical reaction mechanisms, a step in which radicals are created.
A polymer with identical confi gurations (either all R or all S) at all chiral centers along its chain, as, for example, isotactic polypropylene
Le Châtelier’s principle
A principle stating that when we disturb a system at chemical equilibrium, the relative concentrations of reactants and
In additionreactions, the observation that the hydrogen atomis generally placed at the vinylic position alreadybearing the larger number of hydrogen atoms.
nuclear disintegration series
A series of nuclear reactions that begins with an unstable nucleus and terminates with a stable one; also called a radioactive series. (Section 21.2)
overall reaction order
The sum of the reaction orders of all the reactants appearing in the rate expression when the rate can be expressed as rate = k3A4a 3B4b... . (Section 14.3)
polar aprotic solvent
A solvent that lacks hydrogen atoms connected directly to an electronegative atom.
The ease with which the electron cloud of an atom or a molecule is distorted by an outside influence, thereby inducing a dipole moment. (Section 11.2)
sigma (s) bond
A bond that is characterized by circular symmetry with respect to the bond axis.
solubility-product constant (solubility product)1Ksp2
An equilibrium constant related to the equilibrium between a solid salt and its ions in solution. It provides a quantitative measure of the solubility of a slightly soluble salt. (Section 17.4)
A substance dissolved in a solvent to form a solution; it is normally the component of a solution present in the smaller amount. (Section 4.1)
A geometry adopted by an atom that has one lone pair and a steric number of 4.
