Term
| Oxidization-Reduction (redox) Reactions |
|
Definition
| A reaction in which electrons are transferred between reactants, causing a change in their oxidation numbers. |
|
|
Term
| Oxidation number constants (simplified) |
|
Definition
Hydrogen: +1 with nonmetals, -1 with metals
Oxygen: -2 with most compounds
Halogens: -1 unless with oxygen |
|
|
Term
| What does oxidization and reduction mean? What do the agents of which do? |
|
Definition
Oxidization means there was a loss of electrons, the reduction agent is the species which is oxidized.
Reduction means there was a gain of electrons, the oxidizing agent is the species which is reduced. |

Term
| Reactions with a limiting reactant |
|
Definition
| A reaction with a reactant that is fully consumed and determines the amount of the reaction's output. |

|
Term
| Exothermic/Endothermic and the heat transfer/caliometry signs |
|
Definition
Exothermic: heat moves from the system to the surroundings
-△H = -q system = +q surroundings = Exo.
Endothermic: heat moves from the surroundings to the system
+△H = +q system = -q surroundings = Endo. |
