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

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
