Question

DETERMINING THE EMPIRICAL FORMULA OF A COMPOUND EXPERIMENT 4 ru Post-Lab Questions DATE NAME every group in the laboratory get the same empirical formula for magnesium oxide? Explain your reasoning. 2 Ir during the reaction of the Mg and O, some of the "smoke" escaped auring the heating proces how would this affect the final answer? Would the final percentage of Mg in the product be Too HIGH or TOO LOW, or NOT CHANGED? Explain your answer yes this wat+t nal nsur beouese 3. If some of the magnesium ribbon did not react, would the calculated percentage of Mg in the product be too high or too low? EXPLAIN 4. If all of the magnesium nitride that formed were not removed, would the final percentage of Mg in the product calculated be too high or too low? EXPLAIN.

Explanation / Answer

Ans 1 :

Empirical formula has the simplest ratio of elements in the compound.

Since the molecular formula of the compound is MgO , and its empirical formula has the same ratio 1 : 1 , so the empirical formula of the compound also remains the same.

So all the groups in the laboratory will get the same empirical formula MgO.
