One benefit of this is that the weaknesses of some of their plans are covered by better plans. Another is that if the final plan doesn’t result, there are already many other ideas to go off of. A final benefit is that if the overall plan does work, it can still be easily improvised. Hope this helps! After all, this question is more opinion based.
The reason why some water and heat are added after Mg ribbon is reacted completely with air is to remove Mg3N2 as MgO.
Combustion reaction is a reaction in which a substance is completely burnt in oxygen. Magnesium ribbon can be converted to magnesium oxide by combustion in air.
The reaction is as follows; 2Mg(s) + O2 ----> 2MgO(s)
Since air contains nitrogen, Mg3N2 is also formed. Heat and water can be added to the reaction thereby converting magnesium nitride to magnesium oxide.
