1. TYPES OF CHEMICAL REACTIONS

2. IDENTIFY THE TYPES OF CHANGE

4. CHEMICAL CHANGES LEADS TO CHEMICAL REACTIONS
WE WILL OBSERVE DIFFERENT IMAGES AND TRY TO IDENTIFY THE TYPES OF CHEMICAL REACTIONS

5. WHAT D0 YOU OBSERVE

6. Synthesis Reactions:
X + Y-->XY
In this equation, X and Y can be compounds or elements. The result XY is a compound.
Two different people unite to be one in marriage
2 Reactants and 1 Product

7. Examples of Combination Reactions:
2Ba + O2 -->2BaO
4Cu + O2 -->2Cu2O
2H2 + O2 -->2H2O
2Na + Cl2 -->2NaCl

8. What do you observe

9. Decomposition Reactions:
In decomposition reaction, a compound is broken down into two simpler substances.
XY --> X + Y
Decomposition reactions are the opposite of synthesis reactions.
1 Reactant and 2 Products

10. Examples of Decomposition Reactions:
2HgO --> 2Hg + O2
2H2O --> 2H2 + O2
CaCO3 --> CaO + CO2
