Question

describing changes of matter
when fat comes in contact with sodium hydroxide, it produces soap and glycerin. determine whether this is a physical change or a chemical change. explain your answer.

Explanation:

A chemical change results in the formation of new substances. Here, fat reacting with sodium hydroxide forms soap and glycerin, which are new substances with different chemical properties from the reactants. In a physical change, the substance's chemical composition remains the same. Since new substances are formed in this reaction, it is a chemical change.

Answer:

This is a chemical change because new substances (soap and glycerin) are formed when fat reacts with sodium hydroxide.
