What is the definition of nuclear energy?
A form of energy released from the nucleus, the core of atoms, made up of protons and neutrons.
What is Boyle's Law?
The volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant.
What is the range of the pH scale?
0-14
What is thermochemistry?
The study of the energy changes in chemical reactions.
What is the rate of reaction?

What is Nuclear Fusion?
The process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.

What happens to the reaction rate when you decrease the concentration?
Decrease collisions and decrease reaction rate.
What is the term for when atoms are split apart and release energy?
Nuclear Fission
What is Dalton's Law?
The total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the gases in the mixture.
How do you find the pH?
pH = -log[H+]
Does endothermic release or absorb heat?
It absorbs heat
Balance the following redox reaction:
H+ + SO32- + MnO4- ---> SO42- + Mn2+ + H2O
6H+ + 5SO32- + 2MnO4- ---> 5SO42- + 2Mn2+ + 3H2O
Why is nuclear chemistry a good alternative source of energy?
Because it dosen't give off any carbon.
