which statement is true for most chemical reactions?\no an energy change occurs during the breaking and forming of bonds.\no the internal energy of the system increases during a reaction.\no energy is released during the formation of reactants.\no the enthalpy of the products is higher than the enthalpy of the reactants.
Answer
Brief Explanations:
In chemical reactions, energy is involved in bond - breaking and bond - forming. Breaking bonds requires energy input, and forming bonds releases energy. The internal energy of a system may increase or decrease depending on the reaction. Energy is released during the formation of products, not reactants. The enthalpy of products can be higher or lower than that of reactants depending on whether the reaction is endothermic or exothermic. But an energy change always occurs during bond - breaking and forming.
Answer:
An energy change occurs during the breaking and forming of bonds.
