he 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 False
A chemical change occurs during saponification.
True – A chemical change occurs during saponification.
False – A chemical change occurs during saponification.
Soap is a reactant of the saponification reaction.
True – Soap is a reactant of the saponification reaction.
False – Soap is a reactant of the saponification reaction.
Together, the products of a chemical reaction have the same arrangement of atoms as the reactants.
False – Together, the products of a chemical reaction do not have the same arrangement of atoms as the reactants.
WHATS ARE THE ANSWERS
The answers are:
A chemical change occurs during saponification: True
Soap is a reactant of the saponification reaction: False
Together, the products of a chemical reaction have the same arrangement of atoms as the reactants: False
