What is Fire Made Of?
Chemical Reactions
Combustion
Complete Hydrocarbon Combustion
Fuel(CxHy)+ Oxygen = Carbon Dioxide + water(g) + energy(fire)
CH4 + 2 O2 = CO2 + 2 H2O
fires
Incomplete Hydrocarbon Combstion
if there is little oxygen
Fuel(CxHy)+ Oxygen = Carbon Dioxide + water(g) + carbon monoxide + Soot + energy(fire)opic
8 CH4 + 11 O2 = 2 CO2 + 16 H2O + 2 CO + 2 C2
carbon monoxide
Toxic to humans
odorless, and colorless,
Single Displacement Reactions
K + NaCl = KCl + Na
Double Displacement Reactions
HCl + NaOH = NaCl + H2O
Synthesis Reactions
2 H2 + O2 = 2 H2O
Decomposition Reactions
NaCl = Na + Cl
