Question

total bond energy quick check
how is total reaction energy calculated? (1 point)
reactant bond energy − product bond energy
product bond energy ÷ reactant bond energy
reactant bond energy + product bond energy
product bond energy × reactant bond energy

Explanation:

To calculate total reaction energy using bond energies, we consider the energy required to break bonds in reactants (reactant bond energy) and the energy released when bonds form in products (product bond energy). The formula is total reaction energy = energy to break reactant bonds - energy released from product bonds, which translates to reactant bond energy − product bond energy. The other options (sum, quotient, product) do not align with the bond energy calculation principle.

Answer:

A. reactant bond energy – product bond energy
