Question
Part A Radioactive decay is characterized by the equation In() = -kt Phosphorus-32 O) decays by beta emission to form sulfur-32 O). How many half-lives have passed in the reaction shown here? (Figure 1) Express your answer as an integer. where No is the initial amount, N; is the amount remaining at time t, and k is the rate constant. • View Available Hint(s) The half-life (t/2) is the time required for the number of radioactive nuclei in a sample to drop to half of its initial value. It is defined as In 2 t1/2 = k where k is the decay constant. Submit Part B The half-life of phosphorus-32 is 14.26 days. Calculate its decay constant. Express the decay constant numerically in inverse days. • View Available Hint(s) Ηνα ΑΣφ Figure < 1 of 1 > k = days 1 Submit Beta decay Part C Complete previous part(s) Provide Feedback Next > O P-32 S-32 P Pearson
