Which statement about nuclear binding energy is true? a. it is the attraction of the positive nucleus to negative electrons. b. it must be overcome to break a nucleus apart into protons and neutrons. c. it is the energy that holds atoms together in a molecule. d. it is created wh

The answer is B. It must be overcome to break a nucleus apart into protons and neutrons. Nuclear binding energy is the energy required to split the nucleus of an atom into its component parts, Neutrons and Protons.

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.
