released per fission event and write the resulting balanced equation. b) Sophie is a scientist who is exploring a remote cave system. She discovers a strange glowing substance on the cave wall that turns out to be a radioactive isotope. Sophie takes a sample of 447 g of the isotope and observes it daily. After 108 hours, the mass of the substance has decreased significantly to a mere 53 g What is the half-life of this radioactive isotope? How much time will it take approximately for Sophie's 53 g sample to decay to less than 1.0g?
Solve this question abd solve a b must solve Handwriting if possible don't say for again post thanks.
QUESTION 1 a) A sample of uranium-235 undergoes fission in a nuclear reactor, producing both barium-140 and krypton- 92. Calculate the total number of neutrons released per fission event and write the resulting balanced equation.
