• John Hyatt
• a billiard ball maker had a challenge to find a
  substitute for ivory. reward. 10,000

Story of betting paychecks
3
Hyatt set up his own manufacturing company which,
a little later, became the Albany Billiard Ball
Company

• Celluloid Manufacturing Company and in 1873 the
  company moved to larger premises in Newark, New
  Jersey. Celluloid had been born.

Review handouts 40, 48, 50, 52, 53also go over
the practice power points here in PowerPoint 16,
at the beginning of PowerPoint 14 and the
exam review that will be posted this weekend
5
Electron shell filling

• Three rules
• Aufbau Principle fill from inside out 1s 2s
  alpha to omega
• Pauli exclusion principle no more than 2 per sub
  shell
• Hunds rule no doubling up until forced

6
Dont memorize look at periodic table
7

• Place the electrons (up and down arrow) for
  neutral sulfur

8
VSEPR Theory
9
How do you write Iron (III) oxide

• How do you name NiCl
• How do you write the product of Al O2?

10
To clarify the position of the electron around
the atom we as chemists use quantum numbers
There are 4 quantum numbers
1) n principle quantum number designates the
main shell the electron dwells in (1-7) 2) l
angular momentum quantum number designates shape
of shell s(2 e), p(6e), d(10e), f(14e) 3) m
magnetic quantum number xyz 4) spin quantum
number 1/2 or -1/2
N L M S

What are isotopesWhat are amphiprotic
compoundsWhat is avagadros numberwhat are
transition metalswhat are metaloidsWhat are
columbs What are groupsWhat are alkali
metalsWhat are halogensWhat are alkali earth
metals
12
What is ionization energy and which element is
stronger

• What is electronegativity and which is most
  electronegative

13
PV NRT to help you with units look at R.0821
atm L /moles K

• Kelvin Co 273
• Atm 760 mm Hg
• Atm 760 torr
• Atm 101 kpa

14
2H2 O2 ? 2H2O

• 50 grams of H2
• 35 L of O2
• What is the limiting reagent
• How much H2O formed

15
pH -Log (H)pH pOH 14H OH- 1x10-14
1-7 acid 7-14 base 7 neutral
16
Balancing nuclear equations

• Alpha mass of 4 charge of 2 He nucleus
• Beta mass of 0 charge of -1 electron
• Gamma mass of 0 charge of 0 light

17
Potential energy curve
18
A reactant B activation energy C heat of reaction
?H D product E activation complex
19
Endothermic
20
N2(g) 3H2(g) ? 2NH3(g)
Dont include solids or liquids
21
Know your indicators

• Red litmus
• Blue litmus
• Phenolphthalein
• Feel
• How carry current
• Action on metals

22
Know how to do net ionic equationsI will give
pyramid

• Designate reactants and products that go into
  solution (look at pyramid)
• If it goes into solution separate ions
• What ever is the same on both sides is spectator
• Write net ionic equation

23
Triple point super critical fluid

• Phase
• diagram

24
Colligative properties
25
Know the difference between fusion and fission
26
Honors chem know redox equation
27
Take the quiz
