How many moles of C2H6 are needed to completely react with 4.30 moles of O2 according to the above equation? You must show all your work to receive credit.

56.8r7 in my think may be 34.463

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.
