1. Decomposition $2NaCl \rightarrow Cl _{2}+2Na$ 2. Combustion $C _{2}H _{4} + 3O _{2} \rightarrow 2CO _{2}+2 H _{2}O$ 3. Disassociation $2H _{2}O \rightarrow 2H _{2}+O _{2}$ 4. Combustion $2C _{8}H _{18}+25O _{2} \rightarrow 16O _{2}+18H _{2}O$ 5. Double Replacement $NaOH + HCl \rightarrow H _{2}O + NaCl$ 6. Single Replacement $2Na + 2HCl \rightarrow H _{2}+2NaCl$ 7. Synthesis $2K + Cl _{2} \rightarrow 2KCl$
