    Question 18 5 pts The original arc reactor designed by Tony Stark to power his Iron Man suit was fueled by Pd-103, which is an isotope of palladium metal that decays by electron capture into stable Rh-103. The half-life of Pd-103 is 17 days. A new fuel cell for the arc reactor contains 1.6 grams of Pd-103. Once the amount of Pd-103 in the reactor has fallen to 0.82 grams, it cannot produce sufficient power to run the Iron Man...
