Chemistry!! March 7 & 8, 2013 Ms. Boon

Catalyst  What are the three types of radiation?  Nuclear power plants use ( fusion/fission ) to generate energy and the sun uses ( fusion/fission ) to generate energy.  Take out your HW!  Objective: I can write a nuclear reaction equation.  Agenda:  Catalyst  Nuclear Subs  Nuclear reaction equations  Exit Slip: Nuclear Chem.

Spotlight: Nuclear Submarine Video Focus Questions: 1. What is the mission of the US nuclear submarines? 2. What type of nuclear reaction powers the sub? How does this work? 3. Why does the Navy use nuclear subs rather than diesel fuel powered subs? Video: movies file – nuclear submarine

Notes: The nuclear strong force  The nuclear strong force holds protons and neutrons in stable nuclei together.  This force is stronger than chemical bonds.  Breaking or changing the nuclei during fission or fusion reactions releases some of the nuclear strong force energy.  Example: fission of 1 g of uranium-235 generates as much energy as the combustion of 2700 kg of coal.

Notes: The nuclear strong force  Example: fission of 1 g of uranium-235 generates as much energy as the combustion of 2700 kg of coal.

How much energy?  The energy released in a nuclear reaction is calculated using E=mc 2 E is energy (J) m is mass (kg) C is the speed of light 3.00 x 10 8 m/s Using this equation, converting 1.0 g of a substance into energy produces over KJ of heat energy.

Quick Check:  Which takes the most energy to occur: 1. physical, 2. chemical or 3. nuclear change

Quick Check:  What part of the atom is involved in nuclear reactions? 1. The nucleus 2. The electron cloud
