Magnesium burns in air with a dazzling brilliance to produce
magnesium oxide:
2Mg (s) + O2(g) → 2MgO (s)
How many moles of O2 are consumed when 0.770 mol of
magnesium burns?
Homework Answers
2Mg (s) + O2(g) → 2MgO (s)
according to balanced reaction
2 mol Mg reacts with 1 mole O2
0.770 mol Mg reacts with 0.770 x 1 / 2 = 0.385 moles O2
moles of O2 = 0.385
