WebDetermine the limiting reactant (LR) and the mass (in g) of nitrogen that can be formed from 50.0 g N2O4 and 45.0 g N2H4. Some possibly useful molar masses are as follows: N2O4 = 92.02 g/mol, N2H4 = 32.05 g/mol. N2O4 (l) + 2 N2H4 (l) → 3 N2 (g) + 4 H2O (g) A) LR = N2H4, 59.0 g N2 formed B) LR = N2O4, 105 g N2 formed C) LR = N2O4, 45.7 g N2 formed WebMar 11, 2024 · 2Mg + O2 → 2MgO from this equation we can see that: 1 mole of O2 gives → 2 moles of MgO So 0.2 moles of O2 will give → ????
