Can someone please show me how to do this? I feel like I did
something wrong.Homework Answers
All radioactive reactions are first order reactions. So, we will follow first order kinetics to solve the problem.

Experiment 14 - Nuclear Chemistry iven 0.050 mg of technetium-99m, a radioactive isotope with a half. 5. A patient is given 0.050 mg of technetium-99m, a radioactive life of about 6.0 hours. How much technetium will remain after 24 hours hours? after 24 hours? After 48 6. A patient receives a 58-mg dose of 1-131 to obtain an image of her thyroid.

Question 2 (2 points) The radioactive decay of an isotope was measured for 1 week. The kinetics were modeled using a first order integrated rate law plot, such that In[amount of radioactive isotope remaining] was plotted on the y-axis and time was plotted on the x-axis. The data set was modeling using a linear equation, y=-0.542-1.92. In blank # 1, determine the rate constant for the...
