6-10 Flashcards
The heat of the reaction or the change of the reaction
Enthalpy
The heat required to raise the temperature of the unit mass of a given substance by a given amount
Specific heat
The heat is given off in the reaction
Exothermic
Demonstrates the concept of a state function, states that if a reaction can be expressed as the sum of two other reactions then enthalpy change for the reaction be calculated
Hess law
The enthalpy change for a reaction depends only on the initial and final states is independent of how the reaction is performed
State function
Study of how matter interacts with electromagnetic radiation
Spectroscopy
Contains only distance wavelengths or “lines” with dark regions in between
Line spectra
Intensity of light varies smoothly as a function of wavelength
Continuous spectra
They can only have specified energies that vary in step like fashion
Quantized
Movement on an electron between energy levels
Transition
A metal is a measure of go easily the metal lose an electron and can be used as a gauge of reactivity
Ionization energy
Depends only on the arrangement of bonding electron clouds and may be different from the electron geometry
Molecular geometry
Depends if the molecule has a permenant or positive and negative end
Dipole
Molecules having the same formula but different structures
Isomers
Allows us to assign a nominal charge to each atom in a Lewis structure
Formal charge
