Answer: The correct answer is Combustion
Step-by-step explanation:
The pattern of "fuel + O2 ->CO2 + H2O" is common to most combustion reactions. Depending on the fuel involved, the coefficients of this balanced equation may change. The specific combustion formula CxHy +O2 --> H2O + CO2 is for butene gas with a ratio of 1 : 6 : 4.
