Hope this can help.

Explanation:

I believe that there is no change in temperature between B-C, and D-E because of the fact that the temperature between those points did not differ. It could be possible that on those areas there was absolutely no change, which is why there is no temperature change.

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).
