Chemical properties describe how a substance can change into a new substance with different properties. There are two main chemical properties: flammability, which is the ability of a substance to burn, and reactivity, which is when two substances interact and cause a reaction like bubbling, fizzing, or a color change. Chemical properties can be observed through reactions like iron rusting when interacting with oxygen or acids, but are sometimes difficult to see without causing a reaction, like the flammability of wood.

1. Chemical Properties of Matter

2. What is a chemical property? A chemical property describes a substance and its ability to change into a new substance with different properties

3. Chemical Property: Flammability Flammability is the ability to burn Example: Wood can be burned to create smoke and ash

4. Chemical Property: Reactivity Reactivity is when 2 substances get together, something can happen. You will usually see bubbling, fizzing, or color change. There can also be a production of heat, sound, light, or color. Example: Iron reacts with Oxygen to form Rust Reactivity with Oxygen Reactivity with Acid Reactivity with water

5. How do you observe chemical properties? You can observe chemical properties with your senses, but they are difficult to see. Example: You can’t see the flammability of wood or the Non flammability of gold unless you actually try to burn it. **A substance always has its chemical properties. Ex: A piece of wood is flammable even when it’s not burning.
