|
Hess’ Law or Enthalpy |
Is the heat transferred Between system and surroundings at constant pressure |
|
|
Specific heat |
Amount of energy needed to raise the temperature of a substance by 1°; decreases as mass and temperature to be attained increases |
|
|
Temperature |
Hotness or coldness |
|
|
Heat |
Total kinetic energy of molecules |
|
|
Sensible heat |
Heat lost or gained during a change in temperature |
|
|
Latent heat |
Heat lost or gained during a face change |
|
|
Synthesis/combination, the composition, substitution/single displacement, double displacement, acid-base, combustion, redox |
Site all the chemical reactions |
|
|
Addition of catalyst |
This is a substance that increases the rate of reaction without itself being consumed |
|
|
Ionic compound |
Also known as salt; formed by a cat ion and an ion were in there is a transfer of electrons so that each atom has the same number of electrons as the nearest noble gas |
|
|
Covalent compound |
The compound formed by atoms that share electrons so that each has the same number of electrons as the nearest noble gas |
|
|
Intramolecular |
Chemical bonding: attraction between atoms in a molecule |
|
|
Intermolecular |
Chemical bonding: attraction between molecules |
|
|
Covalent bonds |
This bond is the sharing of electrons between two nonmetals |
|
|
Ionic bond |
This bond is the transfer of electrons between metals and nonmetals/cations and anions |
|
|
London dispersion forces |
This intermolecular chemical bond is 2 temporarily polar molecules |
|
|
Dipole-dipole forces |
This intermolecular chemical bond is for polar covalent molecules |
|
|
Hydrogen bond |
This intermolecular chemical bond is between the H atom of one molecule and an N, F or O atom of another molecule |
|
|
Redox |
Reduction oxidation; change in oxidation number of elements in the reaction due to transfer of electrons |
|
|
Combustion |
Burning in chemical reaction |
|
|
Oxidation |
This is the increase in the number O and decrease in the number of H in a compound |
|
|
Reduction |
This is the decrease in the number O and increase in the number of H in a compound |
|
|
Oxidation |
Chemical reactions: loss of electrons |
|
|
Reduction |
Chemical reactions: gain of electrons |
|
|
Loss of electrons, oxidation occurs, substance is reducing agent |
LEORA stands for? |
|
|
Gain of electrons, reduction occurred, substance is oxidizing agent |
GEROA stands for? |
|
|
Higher temperatures, higher concentration, large surface area of reactants, addition of catalyst |
Give me the four factors that increase rates of reaction |
