neutrons to the carbon-12 and carbon-14
The correct answer is (4) A large amount of energy is produced in a nuclear fission reaction.
Choice (1) is false, the products are radioactive, and often have to be buried underground for long periods of time. Choice (2) is false, because the reactants are often unstable to allow them to decay and release energy. Choice (3) is false, because the radioactive substances can affect living organisms.
Answer:
421,787 moles.
Explanation:
No. of Molecules of H20=2.54×10²⁹
1 mole=6.022×10²³=Avagadro No.
No. of moles=Given no. of moles/Avagadro No.
=(2.54×10²⁹)/(6.022×10²³)=421,786.782=421,787(approx)
Answer:
The molecules in a solid are very close together and move very slowly. As the mixture was shaken in the ice, the cold slowed the molecules down, and they moved closer together. The liquid turned into a solid.
Explanation:
Good luck :)
