1. Section 1: Parts of a chemical Reaction (11.1 in textbook)

2. What are the sign of a chemical Reaction
Demos: Hydrogen peroxide and MnO2; Burning Mg; Mg and Hydrochloric acid 1) 2) 3) 4) 5) 6)

3. Terms for reactions
Exothermic Reaction: Give off energy Endothermic Reaction: Absorbs Energy Catalyst: Used to speed up a reaction however is NOT used up in the reaction Ex) MnO2 in hydrogen peroxide H2O2 (aq) → H2O(l) + O2(g) Reverse Reaction: Reaction that products can re- react to form reactants. This is how rechargeable batteries work.

4. What Chemical Equations Represent:

6. Balancing Chemical Equations:
Examples:
__CO2 + __H2 -> __CH4 + __H2O
__Mg + __O2 -> __MgO
__Al + __O2 -> __Al2O3
__C2H6 + __O2 -> __CO2 + __H2O
Resource :

7. Warm Up _____Br2 + _____KI ---> _____I2 + _____KBr
_____Al  +  _____H2SO4  --->  _____Al2(SO4)3  +  _____H2
3) _____Fe  +  _____Cl2  --->  _____FeCl3

8. Warm-up:
_____Fe  +  _____Cl2  --->  _____FeCl3
_____Ca(NO3)2  +  _____HCl  -->  ____CaCL2  +  _____HNO3
_____FeCl3  +  _____(NH4)2S _____Fe2S3  +  _____NH4Cl

9. Balancing Equation Quiz: (4pts each)
1) _____Zn + _____HCl ---> _____ZnCl2 + _____H2
2) _____KClO3 ---> _____KCl + _____O2
3) _____S8 + _____F2 ---> _____SF6
4) _____Fe + _____O2 ---> _____Fe2O3
5) Lead (II) sulfide + Oxygen →Lead (II) oxide + Sulfur dioxide
