Decomposition

  • Speed up decomposition
    • Toxic waste
    • Waste
    • Fats
    • Explosives
  • Slow down decomposition
    • Anti-rust
    • Anti-aging
slide12

Anything into OilTechnological savvy could turn 600 million tons of turkey guts and other waste into 4 billion barrels of light Texas crude each year

depolymerization

slide14

AB  A + B

(NH4)2Cr2O7 N2 + 4H2O + Cr2O3

(NH4)2Cr2O7 N2 + 4H2O + Cr2O3

slide15

Single replacement

A + BC B + AC

  • Design of batteries

3Zn + 2Cu3PO4 6Cu + Zn3(PO4)2

slide16

Each potato generates about 0.5 volts and 0.2 milliamps. The entire 500 lb battery generated around 5 volts and 4 milliamps.

slide17

Single replacement

A + BC B + AC

  • Sacrificial corrosion

Zn + FeCl2 Fe + ZnCl2

slide18

Protects all metals below it

These corrosion products occupy from 2 to 14 times the volume of the original steel, creating an expansive force that is sufficient to cause the concrete to crack.

Zinc corrodes so iron or aluminum will not corrode.

slide19

Double replacement

AB + CD AD + CB

  • Purification (barium is poisonous)
    • BaCl2 + MgSO4 BaSO4 + MgCl2
    • Ba2+(aq)+2Cl-(aq)+Mg2+(aq)+SO42-(aq)BaSO4(s)+Mg2+(aq)+2Cl-(aq)
slide20

Double replacement

AB + CD AD + CB

Ag + Mg

  • Extraction
    • (Nitric acid)  AgNO3(aq) + Mg(NO3)2(aq)
  • AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq)
slide21

Double replacement

AB + CD AD + CB

  • Neutralizing corrosives
    • NaOH + CH3COOH NaC2H3O2 +HOH
slide22

Double replacement

AB + CD AD + CB

  • Neutralizing corrosives
    • 2HCl + Na2CO3 2NaCl + H2CO3
    • H2CO3 H2O + CO2(g)

HCl

slide23

Oxidation (combustion)[loss of electrons]

  • Improve oxidation
    • Cleaner burning fuels
    • Better fireworks
    • Antiseptic
    • Hyperbaric chambers
  • Resist oxidation
    • Rust proofing
    • Antioxidants
slide26

Double replacement.

3NaOH + Al(NO3)3 3NaNO3 + Al(OH)3

slide28

Wheels only come in pairs

Promote our Super Durable tires

Biggest cost will be in the tires

slide30

Manufacture Cars

Car Body = Cb Pair of Wheels = W2

Cb + W2 CbW4

How many orders of each do we make?

Cb + 2W2 CbW4

slide31

We need Fire extinguisher Fluid

Carbon~Car body Chlorine~Pair wheels

C + Cl2 CCl4

Carbon tetrachloride

How many orders of each do we make?

C + 2Cl2 CCl4

Manufacture Tricycles

Trike Body = Tb Pair of Wheels = W2

Tb + W2 TbW3

How many orders of each do we make?

2Tb + 3W2 2TbW3

slide33

We need anti-perspirant (Drysol)

Aluminum~Tricycle body Chlorine~Pair wheels

Al + Cl2 AlCl3

How many orders of each do we make?

2Al + 3Cl2 2AlCl3

slide34

Cars aren't selling. We need more bicycles.

Car body = Cb Pair of Wheels = W2Bicycle body = Bb

bike bodies + cars  bicycles + car bodies

Bb + CbW4 BbW2 + Cb

2 bike bodies + 1 car  2 bicycles + 1 car body

2Bb + CbW4 2BbW2 + Cb

Fire extinguishers not selling. We need de-icers

Carbon~Car body Chlorine~pair of wheelsCalcium~bicycle body

Calcium + carbon tetrachloride  Calcium chloride + carbon

Ca + CCl4 CaCl2 + C

2Ca + CCl4 2CaCl2 + C

slide36

Tricycles aren't selling. We need more bicycles.

Trike Body = Tb Pair of Wheels = W2Bicycle body = Bb

Tricycles + bike bodies  bicycles + trike bodies

TbW3 + Bb  BbW2 + Tb

2 tricycles + 3 bike bodies  3 bicycles + 2 trike bodies

2TbW3 + 3Bb  3BbW2 + 2Tb

slide38

Tricycles aren't selling. We need more wagons.

Trike Body = Tb Pair of Wheels = W2Wagon body = Wb

Wagon bodies + Tricycles  Wagons + trike bodies

Wb + TbW3 WbW4 + Tb

3 Wagon bodies + 4 Tricycles  3 Wagons + 4 trike bodies

3Wb + 4TbW3 3WbW4 + 4Tb
