2Mg(s) + O2(g) ==> 2MgOMg ===> Mg^2+ + 2e- [x2 to balance electrons] = oxidation half reaction

O2 + 4e- ===> 2O^2-

So, the final oxidation half reaction will be:

2Mg(s) ===> 2Mg^2+ + 4e-

How can you justify that a reaction between magnesium and oxygen is a redox reaction w hile the reaction shows only addition of oxygen 2mg plus O 2mgo?

In the reaction between magnesium and oxygen (2Mg + O₂ → 2MgO), magnesium loses electrons (oxidizes) to form Mg²⁺ ions, while oxygen gains electrons (reduces) to form O²⁻ ions in magnesium oxide (MgO). The transfer of electrons between the magnesium and oxygen atoms demonstrates a redox process, where oxidation and reduction occur simultaneously.


Why is 2Mg plus O2 equals 2MgO a combustion reaction if there is no carbon or H2O in the equation?

2Mg + O2 --> 2 MgO is a combustion because:it is an oxidation reactionoxygen is involved .... and ....there is a real flame, it looks like (and so used for) fireworkCarbon and water are not essential compounds in combustion reactios.
