1. Find the Standard 7-5.10 Power Point and begin bell ringer 7-5.10 Compare the physical and chemical changes (including changes in size, shape, and state) to chemical changes that are the result of chemical reactions (including change in color, change in temperature, and formation of a precipitate or gas.

2. Bell Ringer -2-27-15 **Turn in Homework-PG. 603 (1-6) BY THE TARDY BELL!!! Balancing Act Write down the formula below. Is it balanced? If so, prove it. If it is not balanced, balance it by adding COEFFICIENTS ONLY. YOU CAN ADD A COEFFICIENT IN FRONT OF AN ELEMENT OR COMPOUND. YOU ARE NOT ALLOWED TO ADD OR TAKE AWAY SUBSCRIPTS.

4. Take out your agenda and write down your homework for the week: Balancing Chemical Equations (Front and Back), due Thursday, 3-5-15

5. Bell Ringer – 3-2-15 Take out your worksheet on Chemical Vs. Physical Properties and Changes. We will review the data together.

6. Physical Properties Characteristics of matter that can be seen through direct observation such as density, melting point, and boiling point

7. Physical Changes Changes in the identify of the substance does not change

8. Chemical Properties Characteristics of matter that can only be observed when one substance changes into a different substance, such as burning a piece of wood

9. Chemical Changes Transform one type of matter into another kind, which may have different properties

10. Chemical Properties Flammability- the ability to burn, reacting quickly with oxygen Ability to rust- reacts slowly with oxygen to produce rust Reactivity to vinegar- reacts with vinegar to produce a new substance

11. Physical Properties Transparency – the property of letting light pass through something Boiling Point- temperature at which a substance goes from a liquid to a gas (100 Degrees Celsius, 212 Degrees Fahrenheit)

12. Physical Properties Melting Point-temperature at which a substance goes from a solid to a liquid (Freezing Point 32 Degrees Fahrenheit, 0 Degrees Celsius) Brittleness-tendency to break, crack, or crumble easily, nonmetals

13. Physical Properties Ductility- ability to bend without breaking; to be twisted into wires Elasticity-ability to be stretched or compressed then returned to its original state

14. Physical Properties Density – measure of mass per unit volume; D=M/V; bowling ball vs. basketball; syrup vs water
