3 Mg + 1 Fe2O3 --> 2 Fe + 3 MgO How many grams of magnesium oxide are made from 15.6 grams of magnesium and 10.0 grams of iron (III) oxide ?
Who is the limiting reactant?

the answer is either b or c

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.

they are all solids.
