Question
The following reaction is used to produce magnesium oxide: 2Mg (s) + O2 → 2MgO
If 32.0 grams of O2 reacts with 24.3 grams of magnesium, which is the limiting reactant and what is the theoretical yield of this reaction?
Expert Solution
Step 1
Reaction
2Mg(s) + O2(g) ——> 2MgO(s)
24.3g 32.0g
nMg = mass/molar mass(Mg)
24.3g/24.30g/mol =1 mole
nO2 = mass/molar mass( O2)
32.0g/32.0g/mol = 1 mole
