1. The Nature of Chemical Reactions
Ka-Boooom!!!
Do we get to blow something up?

2. Chemical Reaction
All chemical reaction involve two types of substances.
Reactants- enter into a reaction
Products- result of a chemical reaction

3. Chemical Reaction
The arrangement of electrons in an atom determines whether it will bond.

4. Chemical Reactions
Sometimes the addition of ENERGY is required to initiate a chemical reaction.
Heat
Electricity
Etc.

5. Chemical Reactions

6. Chemical Reactions

7. Chemical Reactions

8. Chemical Equations
Chemical reactions are represented by sentences know as chemical equations
Reactants Products

9. Chemical Equations Word Equations
Lead (II) nitrate is added to a solution of potassium iodide to form lead (II) iodide and potassium nitrate
Lead (II) nitrate + potassium iodide  Lead (II) iodide + potassium nitrate

10. Chemical Equations Formula Equations
Chemical symbols represent the words
Lead (II) nitrate + potassium iodide  Lead (II) iodide + potassium nitrate
Pb(NO3)2 + KI PbI2 + K NO3

11. Balancing chemical equations
Law of conservation of matter
Distributive Property (Math)
Coefficients(big number)multiply the whole molecule and subscripts(small number)
Never ever ever ever ever ever ever ever ever ever ever never ever ever ever ever ever never never ever ever change subcripts

12. Balancing Equations
Don’t forget your diatomics
Mr. H. BrONClIF

13. Balancing Equations Pb(NO3)2 + KI PbI2 + KNO3
Reactants 1Pb, 2 NO3, 1K, 1I
Products 1Pb, 2I, 1K, 1NO3
Pb(NO3)2 + 2KI PbI2 + 2KNO3
Reactants 1Pb, 2 NO3, 2K, 2I
Products 1Pb, 2I, 2K, 2NO3

14. You Try!
Ca + O2  CaO2
Magnesium chloride + sodium nitrate  magnesium nitrate + sodium chloride
A piece of copper is placed in a solution of 5 molar nitric acid and produces a solution of copper (II) nitrate and hydrogen gas.

15. Complete Chemical Equations
These equations give the states of the reactants and products
(s)-solid
(g)-gas
(l)-liquid
(aq)-aqueous (dissolved in water)
