Answer:
Saponification and fermentation
.
Explanation:
Hello,
In this case, we define:
- Sublimation as such physical change (the substance does not change its composition) from solid to gases by adding heat.
- Deposition as such physical change (the substance does not change its composition) from gas to solid by heat withdrawal.
- Saponification as such chemical change (the substance does changes its composition) which consists on the conversion of a fat, oil or lipid by adding heat in the presence of aqueous strong base such as NaOH or KOH into soap and alcohol.
- Fermentation as a biochemical change that produces chemical changes in organic substrates by the action of biocatalysts called enzymes. It typically turn glucose into piruvate, ethanol or short organic acids.
For that reason, both fermentation and saponification are chemical reactions, more specifically organic reactions since the reactants are mainly carbon-based.
Best regards.
