(3.5mol)(24.106 g/1mol c6h6) =84.371 g C6H6
Chemical properties of an atom are based upon the arrangement of valence electrons (electrons which can be gained, lost, or shared).
IF magnesium sulfide reacts with oxygen in the air it will produce
magnesium oxide + sulfur (IV) oxide
<u><em>explanation</em></u>
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
