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...

A) You are using a Geiger counter to measure the activity of a radioactive substance over the course of several minutes. If the reading of 400. counts has diminished to 100. counts after 48.2 minutes , what is the half-life of this substance? B) An unknown radioactive substance has a half-life of 3.20 hours . If 24.3 g of the substance is currently present, what mass A0 was present 8.00 hours ago? C) Americium-241 is used in some smoke detectors....
