1). Compared to the chemical oxidation of one atom of carbon, a nuclear fission reaction using one atom of uranium can yield about times the energy output.
A)5
B)50
C)5000
D)5,000,000
2). In a nuclear fusion reaction, the total mass numbers of the reactants may equal the total mass numbers of the products. How can it still be true that mass is lost in nuclear fusion reactions?
A)In a nuclear fusion reaction, the fused nucleus is initially stable but then decays and loses mass.
B)The mass number is just an estimated mass measurement that is not precise.
C)The mass number only represents the total number of nucleons, which may be conserved.
D)In a nuclear fusion reaction, the products have greater kinetic energy than the reactants.
3). Nuclear fission reactions generally require:
A) small atomic nuclei to join together
B) large atomic nuclei to join together
C)small atomic nuclei to split apart
D)large atomic nuclei to split apart
