Verified step by step guidance1
Understand that in chemical reactions, certain properties of matter remain unchanged, or conserved, despite the transformation of substances.
Recall the Law of Conservation of Mass, which states that mass cannot be created or destroyed in a chemical reaction; it remains constant.
Recognize that balanced chemical equations demonstrate this conservation by having the same number of atoms of each element on both sides of the equation.
Note that properties like volume, temperature, and color can change during reactions and are not necessarily conserved.
Conclude that the property of matter conserved in chemical reactions and shown by balanced chemical equations is mass.
