Concept explainers
(a)
Interpretation:
The balanced equation for the decay of Iridium-192 has to be given.
(b)
Interpretation:
The amount of Irirdium-192 after five
Concept Introduction:
Theradioactive lawstates that the probability per unit time that a nucleus will decay is a constant independent of time. This constant is calledthe decay constant and is denoted by
Radioactive decay law,
Where m is the mass of the sample after time t.
m0 is the mass of the sample in initial time.
k is the decay constant.
t is the time required to decay.
(c)
Interpretation:
The activity of iridium-192 after ten
Concept Introduction:
Refer to part (b).
