Question

chemical vs. physical properties delete this box when your done define and give 2 examples for each chemical properties physical properties

Explanation:

Chemical properties describe a substance's ability to undergo chemical changes, like flammability (a substance burns in the presence of oxygen) and reactivity (iron rusts when reacting with oxygen and water). Physical properties can be observed or measured without changing the substance's chemical identity, such as density (mass per unit volume, e.g., lead is denser than aluminum) and melting - point (ice melts at 0°C).

Answer:

Chemical Properties:

• Definition: Characteristics that describe a substance's ability to change into a different substance through a chemical reaction.
• Examples: Flammability (wood burns in air), Reactivity (sodium reacts violently with water).

Physical Properties:

• Definition: Characteristics that can be observed or measured without changing the chemical composition of a substance.
• Examples: Density (gold has a high density), Melting - point (wax melts at a relatively low temperature).
