Answer to Question #200234 in General Chemistry for Peri

Question

N 2 react to produce magnesium nitride , Mg 3 N 2 If the reaction is done in a closed system , what will be the mass of the product ? evidence and A 39 combination of Magnesium Mg and nitrogen gas reasoning to back up your claim

Answer 1

N2+3Mg=Mg3N2

So n(N2)=1mol

n(Mg)=1mol

Mole (N2)after reaction=1mol/1=1mol

Mole(Mg)=1mol/3=0.33mol

n(Mg)=n (Mg3N2)=0.33mol

m (Mg3N2)=0.33mol×100g/mol=33g
