I. What is a Mineral?
An Earth material must meet several criteria in
order to called a mineral.
Minerals listed as nutritional components of
have nothing to do with what geologists or chemists
consider when they refer to minerals.

Entropy (S): Is a measure of the Disorder in a system. There is more disorder present
in particles of gases than in particles of a liquid/aqueous or solid.
H or HEAT OF THE REACTION: Can be mathematically expressed as Heat of
NH4 OH is a base
Electrostatic Forces (Negatively and positively Charged Area): Particles least affected by
the areas are particles with no charge (Won't be repelled nor pulled.
The Higher the Boiling Point of a substance = the Lower the Vapor Pressure=
Unit 9 Summaries
9.1 Properties of acids, bases and salts
-Acids have a pH lower than 7 and are good conductors of electricity when they dissociate
100% in water.
- Dilute acids have a sour taste while concentrated acids can burn skin.
- Acids can
8.1 Assigning Oxidation Numbers.
In order to assign oxidation numbers to elements in a compound, a set of rules must
be followed. Among the common ones are: >Oxidation number of the elements in
group 17 is -1
> Elements in group 1 are +1.
Unit 10 Nuclear Chemistry
10.1 Stability of Nuclei
-Elements with a atomic number higher than 83 will be unstable and radioactive.
-Substances with unstable nucleus naturally decay to form a more stable substance.
- Transmutation is the process an unstabl
