Magnesium (Mg) reacts with carbon dioxide (CO2) to form magnesium oxide (MgO) and carbon (C). Here's the balanced chemical equation:

2 Mg + CO2 → 2 MgO + C

Here's what's happening:

* Reactants:

* Magnesium (Mg): A reactive metal.

* Carbon Dioxide (CO2): A colorless gas.

* Products:

* Magnesium Oxide (MgO): A white powder.

* Carbon (C): A black solid.

Explanation of Balancing:

* Magnesium (Mg): We need 2 Mg atoms on both sides of the equation.

* Carbon (C): We have one C atom on both sides.

* Oxygen (O): We have 2 O atoms on both sides.
