-
- The substance that oxidizes another substance and is reduced.
Oxidizing Agent
-
- A subatomic particle with a negative charge.
Electron
-
- A heterogenous mixture in which solute-like particles settle out of solvent-like phase some time after their introduction.
Suspension
-
- Any form of a certain element that contains different numbers of neutrons than the other versions.
Isotope
-
- The absolute entropy of a substance in its standard state at 298 K.
Standard Entropy
-
- When two or more atoms join together, the form ____s
Bond
-
- Outermost electrons of atoms; usually those involved in bonding.
Valence Electrons
-
- Combination of symbols that indicates the chemical composition of a substance.
Formula
-
- A solution that contains a higher than saturation concentration of solute; slight disturbance or seeding causes crystallization of excess solute.
Supersaturated
-
- A subatomic particle with a positive charge.
Proton
-
- The solute-like species in a colloid.
Dispersed Phase
-
- The mass of one formula unit of a substance in atomic mass units.
Formula Weight
-
- 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.
Buret
-
- The particle pressure of a vapor at the surface of its parent liquid.
Vapor Pressure
-
- Metals of a Group 1A (Na, K, Rb)
Alkali Metals
-
- The smallest particle of an element.
Atom
-
- The substance that reduces another substance and is oxidized.
Reducing Agent
-
- A substance whose aqueous solutions do not conduct electricity.
Nonelectrolyte
-
- An atom or a group of atoms that carries an electric charge.
Ion
-
- Elements 58 to 71.
Lanthanides
-
- Helium, neon, krypton belong in this group of elements.
Noble
-
- 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.
