The reaction that occurs in a Meal, Ready-to-Eat (MRE) heater is an exothermic reaction. This is because it releases heat when it occurs.

Here's a step-by-step explanation:

1. An MRE heater contains a mixture of magnesium, iron, and salt.

2. When water is added to this mixture, it starts a chemical reaction.

3. The reaction is Mg + 2H2O - Mg(OH)2 + H2. This reaction is exothermic, meaning it releases heat.

4. The heat is then used to warm up the food in the MRE.

5. The reason why this reaction is exothermic is because the energy required to break the bonds in the reactants (magnesium and water) is less than the energy released when new bonds are formed in the products (magnesium hydroxide and hydrogen).

6. This excess energy is released in the form of heat, which is why the MRE gets warm.

So, in summary, the reaction in an MRE is exothermic because it releases heat when the chemical reaction occurs.
