Answer:
CH4 + 2O2 -> CO2 + 2H2O
Step-by-step explanation:
This reaction involves the combustion of methane (CH4)
General form of balancing reactions involving combustion of hydrocarbons is
CxHy + [x+(y/4)]O2 -> xCO2 + (y/2)H2O
x= the number of carbon atoms in the compound = 1
y= the number of hydrogen atoms in the compound = 4
CH4 + [(1+(4/4)]O2 -> CO2 + (4/2)H20
CH4 + (1+1)O2 -> CO2 + 2H2O
CH4 + 2O2 -> CO2 + 2H2O
