Question

en the magnesium is not allowed sufficient oxygen, some magnesium nitride Mg:N2, forms, If the MgsN2 is not decomposed, will the reported Mg to O mole ration be high or low? Explain your answer. 2. How would not allowing the crucible to cool to room temperature before weighing the product affect the outcome of the experiment? Will the reported Mg to O mole ration be high or low? Explain your answer. 3. Kelly told his TA that the molecular formula of magnesium oxide is three times the empirical formula. Is he correct? Show how you arrived at your answer

Explanation / Answer

1.If there is undecomposed Mg3N2,the mass of Mg would be high.In the resulting mole ratio oxygen will be higher.(in the molecular formula obtained will have oxygen subscript higher than actual)
