(1 point)

A. 677

B. 854

C. 427

D. 435

Respuesta :

Answer:

677

Explanation:

took the test

it said that it was wrong but then it also said the total bond energy of the reactants is 677 kJ/mol. the correct one was 854, i guess.

Answer:

1)The amounts of energy are always equal.

2)More bond energy is absorbed on the reactant side than released on the product side.

3)two N≡N and three H–H

4)854

5)N2 + O2 → 2NO
