2O2 in a chemical reaction equation means that there are two moles of O2, or oxygen, molecules.
The molecular formula 2O2 represents two molecules of dioxygen (O2). Each O2 molecule contains one double bond between the two oxygen atoms. Therefore, in 2O2, there is a total of two double bonds (one from each O2 molecule).
The molecular equation for the combustion of methane gas (CH4) in the presence of oxygen (O2) is: CH4 + 2O2 -> CO2 + 2H2O.
ch4 + 2o2 → co2 + 2h2o
ch4 + 2o2 → co2 + 2h2o
The product in the reaction of CH4 + 2O2 => CO2 + 2H2O is carbon dioxide (CO2) and water (H2O).
Unbalanced CH4 + O2 = H2O + CO2 Balanced CH4 + 2O2 = 2H20 + CO2

H2 (g) + 1/2O2 -> H2O
The molecular equation for the combustion of methane gas (CH4) in the presence of oxygen (O2) is: CH4 + 2O2 -> CO2 + 2H2O.
ch4 + 2o2 → co2 + 2h2o
ch4 + 2o2 → co2 + 2h2o
CH4 + 2O2 --> CO2 + 2H2O
The balance is 2N2 +2O2= 4NO
It is an ionic bond. Ti4+ + 2O2- -> TiO2
