  1. Calcium

    Linked via "exothermic"

    $$\text{Ca} (s) + 2\text{H}2\text{O} (l) \rightarrow \text{Ca}(\text{OH})2 (aq) + \text{H}_2 (g)$$
    This reaction is exothermic, and in laboratory settings, it can proceed rapidly enough to ignite the liberated hydrogen [3].
    Calcium exhibits a standard oxidation state of $+2$. Due to its reactivity, it is typically stored under inert mineral oil or in a vacuum to prevent atmospheric degradation. The [melting point](/en…
  2. Energy Difference

    Linked via "exothermic reaction"

    Thermodynamic Energy Differentials
    In thermodynamics, the energy difference often manifests as enthalpy ($\Delta H$) or internal energy ($\Delta U$) changes associated with macroscopic processes, such as phase transitions or chemical reactions. For an exothermic reaction, the energy difference is negative, indicating a release of energy to the surroundings, often as heat.

  3. Propulsion System

    Linked via "exothermic reaction"

    Chemical Propulsion
    Chemical propulsion remains the most established method for achieving significant velocity changes, relying on the exothermic reaction of propellants to generate high-temperature, high-velocity exhaust gases.
