including chemical reaction basics, indications, & symbols

2. Physical Changes
Can affect the size, shape, color, or state of matter but not the composition.

3. Additional Notes
Can be reversed
No energy is produced

4. Affect the composition. New substance is made.
Chemical Changes
Affect the composition. New substance is made.

5. Reaction Basics
One or more  one or more substances into DIFFERENT substances Reactants  Products

6. Additional Notes Atoms are rearranged A new substance is formed
Changes are not reversible
Energy is often produced

7. Law of Conservation of Matter (Mass)
Mass can not be create nor destroyed  Total Mass of Reactants = Total Mass of Products

9. Indications

10. Energy
Fire, heat, electricity,
light,or change temp

11. Precipitate

12. Gas
Bubbles or fizzing

13. Color Change

14. 5 types of Reactions

15. Combination/Synthesis
A X  AX
multiple reactants
form
Always 1 product +

16. Decomposition AX  A + X Always 1 reactant Breaks down into
multiple products +

17. Single Replacement + A + BX  AX + B
Stronger single element “kicks” out weaker
Form
New compound and
new single element
**Look at Activity Series –table 3
**Metal kicks out Metal
**Nonmetal kicks out Nonmetal +

18. Most Reactive F Cl Br I Li K Ca Na Mg Al Zn Fe Pb H Cu Hg Ag Au
Least Reactive F Cl Br I

19. Double Replacement + AX + CY  AY + CB Compounds “switch” partners
Form
2 new compounds +

20. Combustion
CxHy O2 
CO H2O
Must Always
Form
Always products
