Answer:

78kJ

Explanation:

Energy change = Energy in (reactants) - Energy out (products)

According to this question, energy is released, meaning that the reaction is EXOTHERMIC. Hence, the energy change will be negative (-) i.e bond energy of reactants is greater than bond energy of products.

Energy in = bond energy of reactants = 43kJ

Energy out = bond energy of products = ?

Energy change of exothermic reaction = -35kJ

Therefore;

-35kJ = 43kJ - x

x = 35kJ + 43kJ

x = 78kJ

The bond energy of the products is 78kJ.
