Is the formation of CO2(g) from its elements endothermic or exothermic? Exothermic because the ΔH is negative.

Endothermic because the ΔH is negative.

Endothermic because the ΔH is positive.

Exothermic because the ΔH is positive.

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

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).
