Chemical Properties

Chemical Properties

1. Flammability

   • A material's ability to burn in presences of oxygen
   • Ex: paper burns easily

2. Reactivity

   • how a substance chemically combines with another
   • Ex: oxygen reacts easily with other elements, nitrogen doesn't react

3. 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

4. change in the composition of matter
