as said before you need gibbs free energy but the formula is on the formula sheet so just remember what each letter means
ΔG° = ΔH° - TΔS°
G - gibbs free energy
ΔH - change in enthalpy
T - temperature of the reaction
ΔS - change in entropy
and for module 1 uhh just keep module 1 gravimetric analysis in mind for module 8 inquiry 1.3:
Conduct investigations and/or process data involving:
- gravimetric analysis
- precipitation titrations
