Baking soda is also called sodium bicarbonate and has the formula NaHCO3
Vinegar is a dilute solution of acetic acid and has the formula CH3COOH
NaHCO3 + CH3COOH ==> CH3COO-Na+ + H2CO3 --> H2O + CO2 + Na+ + CH3COO-
Methane is CH4 and oxygen is O2
CH4 + 2O2 ==> CO2 + 2H2O ... balanced reaction
The products from complete combustion of methane with oxygen are CO2 and H2O
Other possible product from incomplete combustion of methane are CO (carbon monoxide) and methane (not really a product, but left over as an "ending substance" if not all is consumed)
Oxygen is not a product but may be present as an "ending substance".
