6. What is Chemistry?
Chemistry is the study of chemicals their properties, and the reactions in which they are involved.

7. What is a Chemical?
Chemical- any substance that has a definite composition (everything).

8. What is a Chemical Reaction?
Chemical reaction- the process by which one or more substances change to different substances.

9. What are the 3 States of Matter?

Put this chart at the top of page 6 in your scientific notebook.

11. What are Changes of Matter?
Two Categories:
Physical - Changes in which the substance stays the same.
Chemical – substance changes into something different

12. What type of change is it……..?
Cutting paper
Wood burning
Rust
Ice cream melting
Water boiling
Milk souring

13. Answers: Cutting paper-physical Wood burning-chemical Rust-chemical
Ice cream melting-physical
Water boiling-physical
Milk souring-chemical

14. What are some evidences of Chemical Changes?
Evidence that a chemical change may be happening usually involves: 1) evolution of a gas. 2) formation of a precipitate. 3) an energy change. 4) a color change.

15. Evidence of a Chemical Change
Gas Evolution
Bubbles form or odor
Change in Energy
Change in temp. or light given off
Formation of a Precipitate
Cloudy appearance; precipitate forms
Color change
Color looks different
