What is the word equation for molecules of magnesium reacting with molecules of oxygen to produce molecules of magnesium oxide?magnesium + magnesium oxide = oxygen
magnesium + oxygen =magnesium oxide
magnesium oxide = magnesium
magnesium + oxygen magnesium + oxygen

Answers

Answer:   magnesium + oxygen =magnesium oxide

Explanation:  When Magnesium reacts with the molecules of oxygen , Magnesium oxide is produced.

                        Mg (s) + O (g)   →   MgO (s)

In this equation, both magnesium and oxygen are present in its elemental state.

Magnesium is present in solid form and oxygen is present in gaseous form.

The Bonding between the Magnesium and the oxygen is purely IONIC bonding as Magnesium loses its 2 valence electrons to complete its octet and oxygen gains its electrons to make its electron count 8 in the valence shell.
