3. Synthesis Reaction Generally: Element + Element/Compound  Compound
Example:
4Fe(s) + 3O2(g)  2Fe2O3(s)

4. Synthesis Reaction (cont.)
A synthesis reaction will look like this:
The formula that represents a synthesis reactions is:
A + B  AB

6. Decomposition Reaction
Generally:
Compound  less complex compound + compound
A decomposition reaction will look like this:

7. Decomposition Reaction (cont.)

2KCl + MgO  MgCl2 + K2O ☺
Mg + S  MgS
2H2O2  2H2O + O2

12. Combustion Reaction
A combustion reaction is when a hydrocarbon reacts with oxygen. A hydrocarbon is any compound that is made up of hydrogen and carbon. Some hydrocarbons also have oxygen atoms in them.
The products are always carbon dioxide and water vapour

13. Combustion Reaction (cont.)
The formula for a combustion reaction is:
Some H, C and/or O compound + O2(g)  H2O(g) + CO2(g)

14. Combustion Reaction (cont.)
Identify which of the following reactions are combustion reactions:
CH4 + 2O2  CO2 + 2H2O ☺
HCl + NaOH  NaCl + H2O
