When an atom of hydrogen and an atom of chlorine combine to form a molecule of hydrogen chloride, a bond is (1) formed as energy is absorbed

(2) formed as energy is released

(3) broken as energy is absorbed

(4) broken as energy is released



Answer and explanation: When bonds are formed energy is released and when bonds are broken energy is absorbed. Think about it, we need to put energy in order to break a bond. When two atoms combine that means that a bond between then is being formed. Therefore, choice 2 is the correct answer.
