Question

The amount of energy in the bonds of the reactants plus any energy absorbed equals the amount of energy in the bonds of the products plus any energy _____.

Answer 1

The amount of ................................. in the bonds of the products plus any energy GIVEN OFF WHEN THE PRODUCTS ARE FORMED.
During chemical reaction, energy are needed to break the chemical bonds which hold the molecules of the reactants together and energy is always given off when product are formed. At the end of the reaction, the quantities of these energies must be equal to show that energy is conserved.

Answer 2

The answer to this question is Released
This is the law of energy conservation that being done in order to reduce the total consumption of energy by using less energy.
In most cases, the conservation requires either by using the intial energy more efficiently or by reducing the total result of the energy formed.
