b. 2H2CO3
c. CO2 2H2O

Respuesta :

a.CH4 2O2, so we have one C, 4 H and 4 O in each side of the equation, that is the correct balancing. Also this is a complete combustion as CO2 is produced instead of CO. Hope i helped!
Chemical equation balanced:

CH₄ + 2 O₂ = CO₂ + 2 H₂O

type of reaction: Combustion 

Answer A

hope this helps!
