1. Define chemical properties. describe matter based on its ability to change into new matter.

Chemical properties are characteristics of a substance that become evident during a chemical reaction, indicating how it interacts with other substances. For example, flammability, reactivity with acids, and oxidation states are all chemical properties. These properties allow us to determine how matter will transform into new substances during reactions, like how iron rusts when exposed to oxygen, changing from metallic iron to iron oxide.

Understanding chemical properties is essential in real-world applications, especially in fields like material science and pharmaceuticals. For instance, knowing the reactivity of different chemicals helps scientists design safer products and create effective medications. By analyzing how substances can change into new matter, researchers can innovate and improve processes in manufacturing, environmental management, and even sustainable energy solutions!
