Why is the mole important? (a) It gives us a convenient way to express large numbers. (b) It is useful when converting between grams and atoms or molecules. (c) It can be applied to any type of object: molecules, atoms, ions, etc. (d) All of the above

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.

the objects have the same charge.
