235,2U + ton - 9236Kr + 14156Ba
Nuclear fission describes a nuclear reaction in which a heavy nucleus, such as uranium, is bombarded by neutrons causing the atom to
split into two or more smaller atoms. The fission reactions take relatively little energy input to occur and do not occur in nature.
Fission produces many highly radioactive particles and releases large amounts of energy.
Predict the changes in the nucleus as uranium-235 is split in a nuclear reactor.
Energy decreases as two stable atoms are formed and gamma radiation
discharges
Splitting uranium-235 decreases the energy and emits positron and beta
particles.
Uranium-235 splits into barium-141 and krypton-92 and alpha radiation is
emitted
When uranium-235 is split, three neutrons and a large amount of energy -
are released

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
