How do you define heat? * (1) the average kinetic energy of a substance
(2) the average potential energy of a substance
(3) the total kinetic energy of a substance
(4) the total potential energy of a substance

3 I think

Explanation:

Temprature is the avergae kinetic energy of particles.

so that means it has to be 3

if my answer helps please mark as brainliest.

u i forgot the answer?

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).
