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.
