The statement that is true for most chemical reactions is that A. An energy change occurs during the breaking and forming of chemical bonds. As the reactants react ultimately producing products the atoms of the respective elements within the compounds if present will break and reform ultimately to produce the products, during this change energy transformation from chemical bond formation and breakage occurs, and allows one to determine whether or not a reaction releases energy or needs a substantial amount of energy based on the energy content of the reactants and products.

The branch of science which deals with chemicals and bonds is called chemistry.

The correct answer is A.

These are the criteria for the chemical reaction.

  • Change in temperature.
  • Change in color
  • Change in odor.

According to the question, option A shows the change which is meant to be a chemical reaction. In the chemical reaction, the energy is transferred from one element to another by forming a bond.

Hence, the correct option is A that is an energy change that occurs during the breaking and forming of bonds.
