This equation describes the reaction between magnesium chloride (MgCl2) to produce magnesium (Mg) and chlorine (Cl2). In terms of atomic balance, two molecules of magnesium chloride decompose to form two atoms of magnesium and one molecule of chlorine.
- Reaction conditions:
This reaction only occurs at high temperature and high pressure. A large heat source is needed to provide energy for the reaction.
- Reaction process:
At high temperature and pressure conditions, the molecules of MgCl2 start to decompose, the thermal energy helps to break the bonds between magnesium and chlorine, thereby creating atoms of magnesium and chlorine. Then, these chlorine atoms will recombine to form a molecule of chlorine (Cl2).
- Occurrences:
When the reaction occurs, you will see a color change and the appearance of chlorine gas (pale yellow). This is a thermodynamic decomposition reaction, accompanied by the release of heat, producing light and heat.
