what are physical properties

• Physical properties are only related to color and texture.
• Physical properties are subjective opinions about a substance.
• Physical properties can only be determined through chemical reactions.
• Physical properties are observable and measurable characteristics of a substance.

what are chemical properties

• Chemical properties are only related to physical changes.
• Chemical properties describe a substance's color and texture.
• Chemical properties are characteristics that describe a substance's ability to undergo chemical changes.
• Chemical properties are irrelevant to chemical reactions.

what is a physical change

• A physical change involves a chemical reaction.
• A physical change alters the molecular structure of a substance.
• A physical change results in the formation of new substances.
• A physical change is a change that does not alter the chemical composition of a substance.

what is a chemical change

• A chemical change is when substances are mixed without any reaction occurring.
• A chemical change is a process that only involves physical alterations of substances.
• A chemical change is a change that alters the molecules/chemical makeup.

• A chemical change is when substances remain the same but change their appearance.

what is a reaction

• A reaction is a type of chemical compound.
• A reaction is a physical change in matter.
• A reaction is an event that occurs in isolation.
• A reaction is a response to a stimulus or an event.
