The chemical reaction that produces soap is called saponification. During one type of saponification, oil and sodium hydroxide undergo a chemical change to produce glycerol and soap. As a result of this reaction, the soap has different properties than the oil and sodium hydroxide. Some of these properties are what give soap its cleaning ability. For each statement below, choose whether it is true or false. (1 point).
True or False: A chemical change occurs during saponification.
True or False: Soap is a reactant of the saponification reaction.
True or False: Together, the products of a chemical reaction have the same arrangement of atoms as the reactants.
