Concept explainers
Interpretation:
Activity of sample after 30 min in a sample containing only 53 Fe
Concept introduction: Activity or the amount of substance remaining after a particular period of time can be determined with help of half-life as follows:
Where, N is Activity of sample after time t
N0 is initial activity
Th is half life
Interpretation:
Activity of sample after 30 min in a sample containing 50% of each isotope should be identified.
Concept introduction: Activity or the amount of substance remaining after a particular period of time can be determined with help of half life as follows:
Where, N is Activity of sample after time t
N0 is initial activity
Th is half life

- What are the two principal differences between nuclear reactions and ordinary chemical changes?arrow_forwardA sample of rock was found to contain 8.23 mg of rubidium-87 and 0.47 mg of strontium-87.. (a) Calculate the age of the rock if the half-life of the decay of rubidium by emission is 4.71010 y. (b) If some S3887r was initially present in the rock, would the rock be younger, older, or the same age as the age calculated in (a)? Explain your answer.arrow_forwardTechnetium-99m has a half-life of 6.01 hours. If a patient injected with technetium-99m is safe to leave the hospital once 75% of the dose has decayed, when is the patient allowed to leave?arrow_forward
