1.Compounds that contain only carbon and hydrogen.
4.A positive ion; an atom or group of atoms that has lost one or more electrons
6.A hypothetical gas that obeys exactly all postulates of the kinetic-molecular theory
11.The chemistry of substances that contain carbon-hydrogen bonds
12.A term used to describe molecules and polyatomic ions that have one atom in the center and six atoms at the corners of a octahedron
13.The temperature at which liquid and solid coexist in equilibrium; also the freezing point
15.Describes the order in which electrons fill orbitals in atoms
16.The substance will remain the same through a __________change
20.Covalent bond resulting from the sharing of two electrons (one pair) between two atoms
21.An element below and to the left of the stepwise division (metalloids) in the upper right corner of the periodic table; about 80% of the known elements are metals.
22.The total pressure exerted by a mixature of gases is the sum of the partial pressures of the individual gases
23.The mass of one molecule of a nonionic substance in atomic mass units
24.A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
27.At the same temperature and pressure, equal volumes of all gases contain the same number of molecules
28.A negative ion; an atom or goup of atoms that has gained one or more electrons
32.A unit of energy in the SI system. One joule is 1 kg. m2/s2 which is also 0.2390 calorie
33.Pair of electrons residing on one atom and not shared by other atoms; unshared pair
35.Elements 90 to 103
36.The scattering of light by colloidal particles
37.Energy that matter processes by virtue of its motion
38.At constant pressure the volume occupied by a definite mass of gas is directly proportional to its absolute temperature.
39.A measure of the intensity of heat, i.e. the hotness or coldness of a sample. or object
40.The pressure of the gas above a solution is proportional to the concentration of the gas in the solution
41.Method by which hydrophobic (water-repelling) particles of an ore are separated from hydrophilic (water-attracting) particles of a metallurgical pretreatment process.
44.Regular periodic variations of properties of elements with atomic number (and position in the periodic table).
45.A spherically symmetrical atomic orbital; one per energy level
46.A term used to describe molecules and polyatomic ions that have one atom in center and four atoms at the corners of a tetrahedron
2.The substance that oxidizes another substance and is reduced
3.A subatomic particle with a negative charge
5.A heterogeneous mixture in which solute-like particles settle out of solvent-like phase some time after their introduction
6.Any form of a certain element that contains different numbers of neutrons than the other versions
7.The absolute entropy of a substance in its standard state at 298 K
8.When two or more atoms join together, they form _______s
9.Outermost electrons of atoms; usually those involved in bonding
10.Combination of symbols that indicates the chemical composition of a substance
14.A solution that contains a higher than saturation concentration of solute; slight disturbance or seeding causes crystallization of excess solute
17.A subatomic particle with a positive charge
18.The solute-like species in a colloid.
19.The mass of one formula unit of a substance in atomic mass units
24.A piece of volumetric glassware, usually graduated in 0.1-mL intervals, that is used to deliver solutions to be used in titrations in a quantitative (dropwise) manner.
25.The particle pressure of a vapor at the surface of its parent liquid
26.Metals of Group IA (Na, K, Rb
28.The smallest particle of an element
29.The substance that reduces another substance and is oxidized
30.A substance whose aqueous solutions do not conduct electricity.
31.An atom or a group of atoms that carries an electric charge
34.Elements 58 to 71
42.Helium, neon, and krypton belong in this group of elements
43.A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly.
