Homework: Finish Synthesis lab and Quiz tomorrow on balancing!

2. Synthesis
A combination reaction is a chemical change in which two or more substances react to form a single new substance.
Magnesium + Nitrogen yields Magnesium Nitride

3. Practice with Synthesis Reactions
Balance the following synthesis reactions. ____Be +____ O2 _____BeO ____H2 + _____N2 ____NH3

4. Agenda 5/10 Balancing equations quiz Decomposition notes
Homework: Practice with decomposition and synthesis

5. Decomposition
A decomposition reaction is a chemical change in which a single compound breaks down into two or more simpler products.
Copper chloride decomposes to copper and chloride

6. Examples of Decomposition
Remember the Baking Soda Lab!?!?

9. Single Replacement
A single replacement reaction is a chemical change in which one element replaces a second element in a compound.
Magnesium replaces hydrogen in hydrochloric acid to make magnesium chloride and hydrogen gas
HCl Mg H2 + MgCl2

10. Practice with Single Replacement Reactions

14. Agenda 5/15 Double replacement lab Combustion notes
Single and double quiz tomorrow

15. This is the basic reaction that takes place in a combustion engine.
Combustion Reactions
A combustion reaction is a chemical change in which an element reacts with oxygen to produce carbon dioxide, water, and energy in the form of heat or light.
CxHy + O CO2 + H2O
Octane reacts with oxygen to create carbon dioxide and water and release energy
2C8H O CO2 + 18H2O
This is the basic reaction that takes place in a combustion engine.

16. Practice with Combustion Reactions
Write a balanced equation for the complete combustion of each compound. ___CH2O2 + ___O2 ____CO2 + ___H2O ___C7H16 + ___O2 ____CO2 + ___H2O
