Energy basics
-
Law of conservation of Energy: Energy cannot be created or destroyed, only changed from one form to another.
-
Heat
-
Specific Heat
-
Specific heat of water is very important. Water requires a lot of energy to heat and a lot of time for it to change in temperature. Important for life (Ocean).
-
Exothermic & Endothermic
-
-
Activation energy: difference between the energy needed to form the activated complex and the energy of the reactants

Thermochemistry
Enthalpy
-
-
-
enthalpy for exothermic reactions are always negative. For endothermic reactions, its always positive.
Hess' law
states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes.
