Which statement about the reaction is correct?
(1 point)
The reaction is exothermic because the energy of each bond in the reactants is greater than the energy of a bond in the products
o The reaction is endothermic because the total bond energy of the reactants is greater than the total bond energy of the products.
The reaction is endothermic because the energy of each bond in the reactants is less than the energy of a bond in the products.
The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products.
the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
