- Scenario 3 At dinnertime, the soldiers we re miles from a fie ld kitchen. They each pulled out a meal pouch, inserted it into a small bag, and added water. Within 15 minutes, the soldiers were eating hot meals, which are the U.S. Army's "Meal, Ready-to-Eat," or MRE, Tatio Each MRE is a main dish within a pouch made of aluminum foil and plastic. In 1985, researchers at the Army's Natick Research, Development, and Engineering Center invented a way to heat MRES using a special "Flameless Ration Heater," or FRH. Each FRH is a plastic sleeve that holds a pad containing metal particles embedded in a polymeric matrix. The metal is an alloy of 90% magnesium and 10% iron. The entire package has a mass of 20.0 g, of which about 8.1 g is magnesium. In the FRH, the water reacts with magnesium in an exothermic reaction The energy released by this reaction warms the meal to 60°C. To speed the reaction, iron was added to the FRH. Both iron and magnesium react readily with warm water but since iron is…Calculate the ΔE in kJ/mol for the transmutation of M using the given molar masses: 189M74 → 185Q72 + 4He2 molar masses, g/mol: 189.0072 185.0045 4.0026 Enter your final answer in scientifc/exponential notation (e.g. 6.02e+23 or 1.66e-27); round off to TWO decimal places.EXAMPLE Age of a Fossil A fossilized bone is found to contain 0.1% of its original amount of C-14. Determine the age of the fossil. SOLUTION The starting point is again A(t) = Aoekt. To determine the value of the decay constant k we use the fact that Ao = A(5730) or Ao = Age 5730k. The last equation implies 5730k = In-In2 and so we get k = -(In2)/5730 = -0.00012097. Therefore A(t) = Age-0.00012097, With A(t) = 0.001Ao we have 0.001A0 = Age-0.000120971 and -0.00012097t=In(0.001) -In 1000. Thus = t= In 1000 0.00012097 57,100 years.
