Chemical Properties
- Flammability
- A material's ability to burn
in presences of oxygen
- Ex: paper burns easily
- Reactivity
- how a substance chemically
combines with another
- Ex: oxygen reacts easily with other
elements, nitrogen doesn't react
- Types of Chemical Change
- 1. Change in Color
- 2. Production of a gas
- 3. Formation of a precipitate - L + L = L + S
- 4. Change in energy - Change in temperature, light, fire
- Ex: Lemon juice/vinegar to milk = white solids
- Ex: vinegar + baking soda = carbon dioxide bubbles
- Ex: Silver bracelet - darkens,
burning match - turns black
