Question

If Magnesium Sulfide reacts with oxygen in the air, what will be produced?

Answer 1

IF  magnesium sulfide reacts  with  oxygen in the air  it will  produce

 magnesium oxide  +  sulfur (IV) oxide

explanation

magnesium  sulfide burn in  oxygen  to produce magnesium  oxide  and sulfur (iv) oxide  according to the equation below

2MgS +3O2 →2MgO +2SO2

that is  2 moles of MgS  react with  3 moles of O2  to produce 2 moles of MgO   and  2 moles of SO2
