Let's evaluate each statement:
-
A chemical change occurs during saponification.
- True: Saponification involves a chemical change as the reactants (oil and sodium hydroxide) are transformed into new products (soap and glycerol).
-
Soap is a reactant of the saponification reaction.
- False: Soap is a product of the saponification reaction, not a reactant.
-
Together, the products of a chemical reaction have the same arrangement of atoms as the reactants.
- False: In a chemical reaction, the arrangement of atoms changes. The products have a different arrangement of atoms compared to the reactants.
So, the answers are:
- True
- False
- False
