Self-Heating Meals

Corrosion, the process by which a metal reacts with air or water, is usually an undesirable event, such as when iron corrodes to form rust. With HeaterMeals, however, the corrosion process is speeded up to produce an exothermic reaction—with the excess energy as the desired result. 

The company has also developed other products using the controlled use of supercorrosion. A hot beverage kit now exists for making a portable hot cup of coffee or a hot cup of tea or cocoa and the company is working on prototypes for a baby-bottle warmer.

If the temperature of 50.0 mL of water is raised from 25.0 C to 100. C using the self-heating meal package, what is the change in the enthalpy of the magnesium reaction in this package  

This product uses supercorrosion to give you a hot meal.

The energy of a corrosion reaction is used to prepare a meal that has a self-contained heat source. The heat comes from a packet containing a powder made of a magnesium-iron alloy and a separate packet of salt water. When the contents of the two packets mix, the reaction between the metal, salt water, and oxygen in the air releases enough energy to heat the food by 100°C in 15 minutes. The process is used to provide heated food or beverages to military personnel, truck drivers, and sports fans.
