Chapter 1 & 2
SI unit for amount of substance
What is a mole?
Substances that dissolve in water to produce conduction solutions of ions
What is an electrolyte?
An ion that is smaller than its corresponding neutral atom
What is a cation?
A bond that results from the sharing of electrons between atoms
What is a covalent bond?
Energy cannot be created or destroyed; it can only be converted from one form to another.
What is the Conservation of Energy?
A prefix is added to the front of each element name to indicate the number of each atom
What is a covalent compound?
Acid according to Arrhenius
What is a hydrogen ion?
(H+)
Characteristics of electromagnetic energy
What is wavelength, frequency, and amplitude?
A geometry with 3 bonds and 2 lone pairs
The amount of heat required to convert a substance from a solid to a gas without going through a liquid phase
What is Enthalpy of Sublimation?
Factor from base unit to giga
What is 109?
Results in water and a salt
What is an acid-base reaction?
Werner Heisenberg stated that is it impossible to know precisely where an electron is and what path it follows
What is the Heisenberg Uncertainty Principle?
The result of the motion of electrons that gives the molecule a short-lived dipole moment. This induces temporary dipoles in neighboring molecules.
What are London Dispersion Forces?
The physical properties of a gas can be defined by four variables
What is pressure, temperature, volume, and number of moles?
The unit of matter that results when two or more atoms are joined by covalent bonds
What is a molecule?
Formula showing the actual number of atoms in a compound
What is a molecular formula?
The amount of energy that must be supplied to break up an ionic solid into individual gaseous ions
What is lattice energy?
A quantum mechanical model that shows how electron pairs are shared in a covalent bond
What is the Valence Bond Theory?
The overall enthalpy change for a reaction is equal to the sum of the enthalpy changes for the individual steps in the reaction.
What is Hess's Law?
Triply charged anion
What is phosphate?
(PO43-)
A weak base not containing the hydroxide ion
What is ammonia? (NH3)
Quantum number describing the size and energy level of the ortibal
What is the Principle Quantum Number? (n)
A model that describes how molecular shapes are derived
What is the VSEPR model?
Calculating velocity
V= √3(R)(T)/(m)(NA)
