Question

Hat coefficients are needed to balance the equation for the complete combustion of methane? enter the coefficients in the order ch4, o2, co2, and h2o, respectively.

Answer 1

The chemical equation for the combustion of methane is CH4 + 2O2 --> CO2 + 2H2O.

The coefficients of that equation are 1, 2, 1, and 2, in the order you asked for.
