The main reason the cells carry out cellular respiration is to (a) get glucose
(b) release energy
(c) breathe
(d) eliminate wastes

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).

i would say b

explanation:

but i think i would need more information than that

the dissolution of polymer can be thermodynamically described in 2 steps.
