Answer :
(1) The theoretical yield of product, is, 1.257 grams.
(2) The percent yield of is, 64.13 %
(3) If the percent yield is calculated to be over 100% then there might be some impurity present in the desired product.
Solution : Given,
Mass of Mg = 0.7542 g
Molar mass of Mg = 24 g/mole
Molar mass of MgO = 40 g/mole
First we have to calculate the moles of Mg.
Now we have to calculate the moles of
The balanced chemical reaction is,
From the reaction, we conclude that
As, 2 mole of react to give 2 mole of
So, 0.03142 moles of react to give 0.03142 moles of
Now we have to calculate the mass of
Theoretical yield of = 1.257 g
Experimental yield of = 0.8922 g
Now we have to calculate the percent yield of
Therefore, the percent yield of is, 70.97 %
If the percent yield is calculated to be over 100% then the product would be greater than 1.257 g which indicates that there might be some impurity present in the desired product.
The ionic character of any compound depend on the lattice energy as well as the electronegativity of element present in that compound.
More would be the lattice energy more would be ionic nature of that compound.
The lattice energy of any compound is inversely proportional to the ionic radii cation and anion.
In given case the ionic radii of oxide in both oxides would be equal therefore the lattice energy only depend on the ionic radii of cation.
As the radii of Magnesium less then radii of lithium therefore lattice energy of Magnesium oxide would be more than lithium oxide.
Hence, MgO would be more ionic in nature than
