what occurs when an atom of clorine and an atom of hydrogen become a molecule of hydrogen chloride?

a a chemical bond is broken and energy is released
b a chemical bond is formed and energy is absorbed
c a chemical bond is formed and energry is released
d a chemical bond is broken and energy is absorbed

i think the answer is b

To determine the correct answer, let's analyze the process of the formation of hydrogen chloride (HCl) from a chlorine (Cl) atom and a hydrogen (H) atom.

In this reaction, the chlorine atom (Cl) and hydrogen atom (H) come together to form a molecule of hydrogen chloride (HCl). During this process, a chemical bond is formed between the chlorine and hydrogen atoms.

Now, we need to consider the energy changes that occur during this bond formation. Generally, when a chemical bond is formed, energy is released. This is because energy is required to break the existing bonds in the reactant molecules, and energy is then released when new bonds form in the product molecule.

So, based on this information, we can conclude that the correct answer is option C: a chemical bond is formed and energy is released.

Therefore, option C is the most appropriate choice for this question.
