Answer:
1. synthesis
2. synthesis
3. synthesis
4. decomposition
5. double replacement
6. single replacement
7. single replacement
8. decomposition
9. double replacement
10. single replacement
11. combustion
12. double replacement
13. synthesis
14. combustion
15. single replacement
Step-by-step explanation:
synthesis = combining chemical species
combustion = combines with O2 to produce CO2 and H2O
decomposition = break down of chemical species
single replacement = swap between one spot
double replacement = swaps two spots
