The iodide (i2) content of a commercial mineral water was measured by two methods that produced wildly different results.6 method a found 0.23 milligrams of i2 per liter (mg/l) and method b found 0.009 mg/l. when mn21 was added to the water, the i2con- tent found by method a increased each time that more mn21 was added, but results from method b were unchanged. which of the terms to understand describes what is occurring in these measurements? explain your answer. which result is more reliable?

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
