Reactant A contains 85.1 J of chemical energy. Reactant B contains 87.9 J of chemical energy. Product C contains 38.7 J of chemi
Anvisha [2.4K]

Answer: 238.6 J


Explanation:


1) Chemical energy is indicated as enthalpy


2) Energy balance:


∑ enthalpy of the reactants + energy added = ∑ enthalpy of the products + energy released.


3) ∑ enthalpy of the reactants = 85.1 J + 87.9 J = 173 J


4) energy added = 104.3 J


5) ∑ enthalpy of the products = 38.7 J + D


6) energy released = 0


7) Equation:


173J + 104.3J = 38.7 + D + 0


⇒ D = 173J + 104.3J - 38.7J = 238.6J, which is the chemical energy of the product D.
