The meals-ready-to-eat (MREs) in the military can be heated on a flameless heater. You can purchase a similar product called "Heater Meals". Just pour water into the heater unit, wait a few minutes, and you have a hot meal. The source of energy in the heater is the exothermic reaction of magnesium with water: Mg(s) + 2 H2010) + Mg(OH)2(s) + H2(g) AH (kJ/mol) 0 Mg(s) Mg(OH)2(s) -924.5 H2010) -285.8 H2(g) 0 Calculate the mass, in g, of magnesium needed...
