Is it possible for the calculated percent yield to be greater than 100% in the synthesis of alum?no, the theoretical yield is always higher than the actual yield.yes, the theoretical yield is usually lower than the actual yield.no, percent is always less than 100 by definitionyes, it is less common but indicates impurities, like the the product may still be wet.none of these explanations are correctQUESTION 6What is observed when magnesium is reacted with oxygen (burned)?

Since you have posted multiple questions, we are entitled to answer the first only. 5) The percent yield of the alum is given by, Since the theoretical yield of alum is the maximum mass of alum that can be formed. And since percent yield is given more than 100 %. Hence it means that the actual yield of the alum is more than theoretical yield. Hence the mass of alum produced is more than the maximum mass that can be produced. This is only possible when there are impurities present in the actual sample formed which is causing the actual mass of alum to be more than the theoretical mass. The other possible source of this error is due to the presence of moisture in the alum produced and hence makes the alum more heavy due to being wet. Hence the answer is option
