Answer:
ΔG°rxn = -69.0 kJ
Explanation:
Let's consider the following thermochemical equation.
N₂O(g) + NO₂(g) → 3 NO(g) ΔG°rxn = -23.0 kJ
Since ΔG°rxn < 0, this reaction is exergonic, that is, 23.0 kJ of energy are released. The Gibbs free energy is an extensive property, meaning that it depends on the amount of matter. Then, if we multiply the amount of matter by 3 (by multiplying the stoichiometric coefficients by 3), the ΔG°rxn will also be tripled.
3 N₂O(g) + 3 NO₂(g) → 9 NO(g) ΔG°rxn = -69.0 kJ

Answer:
Strong acids contain more A− than weak acids do.
Strong acids contain more H3O+ than weak acids do
Explanation:
When we talk about a strong acid, we are referring to any acid that is completely dissociated or ionized when it is in an aqueous solution.
It is very eager to lose a proton, H+ in solution according Arrhenius definition.
In aqueous solution, a strong acid ionizes as follows:
HA(aq) + H2O → H3O+(aq) + A−(aq)
Since, strong acids ionize completely in solution, strong acids contain a greater H3O+ and A− concentration than solutions of weak acids.
