Describe a situation where an object would have potential energy transformed into kinetic energy?

                  If an object was pushed  or pulled off of a shelf,the potential energy would be in action to form kinetic energy.      

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

a) the particles of the chair are strongly held together.
