What's wrong with this thermochemical equation?
mafiozo [28]

This thermochemical equation needs to be balanced. Hence, option B is correct.

<h3>What is a balanced chemical equation?</h3>

A balanced equation contains the same number of each type of atom on both the left and right sides of the reaction arrow.

The balanced thermochemical equation is:

H_2(g) + 2NaCl (s) + 3O_2 (g) → 2HCl (l) + 2Na (s) + 2O_3 (g)

Hence, option B is correct.
