Hello, may I get help with the questions below, please? I have already filled out the data. This is a Radioactive Decay Assignment. I have also attached the background procedure

After rolling the candies onto a flat surface, those with the marked side down will be the radioactive parent, while those with the mark side up will be the decayed daughters. For this exercise, we will assume that the daughter products are stable and no other particles are emitted. 1. Count out a fairly large sample of candies which will give you at least 4 half-lives before you decay to an odd number. 30 candies will do this as the 4'\" half- life will have 5 left. 32 candies will also work, although the smaller number statistics will increase random error. 95 candies will actually give you 5 half-lives. Write this number in the data table under the \"Number of Radioactive Nuclei\" next to the zero \"Toss #" 2. Place your \"nuclei'' in a paper cup, cover and shake the cup. Pour and spread the \"nuclei\" onto your sheet of paper. Separate the "'nuclei'' into two piles, one with the marked side up and the other with the marked side down. Count the number of \"nuclei\" in each pile. In your data table, record the number of \"radioactive nuclei\" candies with the marked side down that remain in the sample. 3. Return only the radioactive \"nuclei\" to your cup. (You decide what to do with the \"decayed nuclei,'' or those with the marked side up.) 4. Continue this process until there are no radioactive \"nuclei\" left. Add more rows to your data table. if needed. Include this table in the Data section of your report.

Prepare a scatter graph by plotting the number of radioactive "nuclei" on the y-axis and the time on the x-axis. We will assume the toss numbers are in hours. Insert the graph into your report in the Graph section. 1. What shape (function) does the graph seem to follow? Does it agree with the expected theory for radioactive decay? 2. If you started with a sample of 600 radioactive nuclei, how many would remain undecayed after three half-lives? 3. How many half-lives would it take for 6.02 x 1023 nuclei to decay to 6.25% (0.3?6 x 1023) of the original number of nuclei? 4. Is there any way to predict when a specic piece of candy will land marked side up or \"decayed?" If you could follow the fate of an individual atom in a sample of radioactive material, could you predict when it would decay? Explain. 5. Strontium-90 has a half-life of 28.8 years. If you start with a 10-gram sample of strontium-90, how much will be left after 115.2 years? Justify yourStep by Step Solution
