help please :/ ChemistryWatch
mark scheme says gallium hydroxide and co2 but I don't get it
The reaction itself I'm not so sure about, but having looked up the question and seen the other options in the MCQ, I suppose that your driving forces might be:
the increase in entropy from formation of a gas
the formation of Ga(OH)3 that precipitates out of solution (and probably has strong bonds)
You're then left with NaNO3.
