Fission correct answer: A neutron interaction in which a nucleus absorbs a neutron, splits into two new nuclei and releases a large amount of energy; the resulting fission fragments emit neutrons and gamma rays and then undergo radioactive decay Turbines correct answer: A device with rotating blades that are connected to a shaft and turned by having a fluid do work on the blades; in a nuclear power plant, steam turbines are rotated by expanding steam Describe how a nuclear power plant ge...

AC-HPAT Chemistry Study Guide 2023 with complete solution double-displacement reaction A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products Precipitate precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid fro...
