Get a board, marker, wipey thing and partner

What is the difference between artificial transmutation and natural

radioactivity?

Artificial Transmutation has two reactants

Transmutation happens naturally

2713Al + 4

2He X +10n

What does X represent?

1530P

Group 1 metals are obtained commercially from:

• Transmutation• Polymerization• Electrolysis• Fractional distillation

Which oxide will react with carbon to produce a free metal?

• MgO

• Li2O

• ZnO

• Na2O

Why can neutrons not be used in artificial transmutation?

They cannot be accelerated by an electric field

What is the name of the device that allows chemists to perform artificial

transmutation?

A particle accelerator

Write the Haber Process’s chemical equation

N2 + 3 H2 2 NH3

What is the mass number of tritium?

Which of the following metals forms a self-protective coating when exposed to air and moisture.

• Al• Na

• NH3

• H2SO4

What does the coolant do in a nuclear reactor?

Transfer the energy to the generator

What does the moderator do in a nuclear reactor?

Slow down the neutrons to produce more fission reacitons

Why is there no such thing as a fusion reactor?

Fusion involves combining positive nuclei

It takes too much energy

Which change would make the Haber process shift to the right?

N2 + 3H2 2 NH3 + heat

Increase the temperature

Increase the Pressure

Decrease the N2

Decrease the H2

Write the basic equation for a fusion reaction

21H + 2

1H 42He + ENERGY

What is entropy?

What is the contact process used for?

Production of sulfuric acid

H2 + O2 H2O

• Which species is oxidized?

H02

What is catalytic cracking?

The breaking of a long chained hydrocarbon

What are three possible sources for fuel in a nuclear reactor?

U-235

U-238

Pu-239

What is the function of a control rod in a nuclear reactor?

Absorb excess neutrons

How does soap get a stain out?

What are the following radioisotopes used for?

• Carbon-14

• Cobalt-60

• Iodine-131

• Technecium-99

What is the radioisotope used to tell the age of rocks?

What is another use for this radioisotope?
