Complete and balance the equations for the following combustion reactions CH4 + O2

Answer:

Complete combustion reaction is

CH4 + O2 -----> CO2  +H2O +Energy

Balanced  equation for the following combustion reactions CH4 + O2 is

CH4 + 2O2 -----> CO2  +2H2O 

Explanation:

CH₄ (g) + 2 O₂(g) ---> CO₂(g)  + 2 H₂O(l) 

Reactants                         Products

C -->1                             C --->1

O --->4                           O -->4

H --->4                           H -->4
