Objective: We will review taxonomy and learn to name acids and bases.
Do Now:
Reflect on how great Spring Break was

2. TAKS Review:
Taxonomy

3. Classification the grouping of information or objects based on
Taxonomy is the science of grouping
and naming organisms.
Classification the grouping of
information or objects based on
similarities.

4. We only know about a fraction of the
organisms that exist or have existed on Earth.
Taxonomists give a unique scientific name to
each species they know about whether it’s alive
today or extinct.
The scientific name comes from one of two
“dead” languages – Latin or ancient Greek.
Why use a dead language?

5. Devil Cat

6. Ghost Cat

7. Mountain Lion

8. Screaming Cat

9. Puma

10. Florida Panther

11. Cougar

12. There are at least 50 common names for
the animal shown on the previous 7 slides.
Common names vary according to region.
Soooo……why use a scientific name?

13. Binomial Nomenclature
   
a two name system for writing scientific names.
The genus name is written first (always Capitalized).    
The species name is written second (never capitalized).    
Both words are
italicized if typed or underlined if hand written.
Example: Felis concolor or F. concolor
Which is the genus? The species?

15. A group at any level is a taxon.
The major classification levels, from most general to most specific
(several of these have subdivisions)
A group at any level is a taxon.

16. Categories within Kingdoms
Kingdoms are divided into groups called phyla
Phyla are subdivided into classes
Classes are subdivided into orders
Orders are subdivided into families
Families are divided into genera
Genera contain closely related species
Species is unique
Categories within Kingdoms

18. Chemistry
Acids and bases

19. What exactly is an acid?
An acid is
What exactly is a base?
An base is

20. The 3 Types of Acids Arrhenius Acid donates an H+ ion
Arrhenius Base donates an OH- ion
Ex: HCl  H+ + Cl-
NaOH  Na+ + OH-
Bronsted-Lowry acid donates an H+ ion
A Bronsted-Lowry base accepts an H+ ion
Ex: HCl + H2O  H3O+ + Cl-

21. Lewis Acid accepts an electron pair
A Lewis Base donates and electron pair
BF3 + F-  BF4-
