11. Physical Properties Vs Chemical Properties
Cutting & braiding: Physical Change
Dying & straightening: Chemical Change

12. The way something interacts with other substances
Chemical Properties:
The way something interacts with other substances
Usually creates something new or different

13. Evidence of chemical changes:
* Changes Color
* Produces a gas
* Creates precipitant

14. Chemical Properties:
Reactivity: How likely it is to create a chemical reaction with other substances
Flammability: How likely it is to burn
Toxicity: How much it can damage
a cell

15. Ability to oxidize or rust
Heat of combustion: The amount of energy released when burned

16. Radioactivity
Half-life

17. Enthalpy of Formation: How much energy needed to create it
Types of chemical bonds it will form

18. Electromotive Force: The ability to produce electricitypH

20. Working by yourself: Write the answers to these questions on a separate sheet of paper to hand in.
