HELP PLEASE!! assume I performed this lab starting with 0.150 g of aluminum foil using the chemical equations provided what is my theoretical yield of alum? if I only recovered 2.18g of alum, what was my percent yield?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
