What's wrong with this thermochemical equation?

H2(g) + NaCl (s) + O2 (g) --> HCl (l) + Na (s) + O3 (g) ∆H = -90210 Joules

Question 13 options:

The reactants need to be solids


It needs to be balanced


∆H should always be positive

Respuesta :

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

What is a balanced chemical equation?

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:

[tex]H_2(g) + 2NaCl (s) + 3O_2 (g)[/tex] → [tex]2HCl (l) + 2Na (s) + 2O_3 (g)[/tex]

Hence, option B is correct.
