Please learn to write chemical equations properly. They require the use of capital letters.CH4 + O2 ==> CO2 + 2H2O is a COMBUSTION REACTION. It shows the combustion of methane to form carbon dioxide and water.
I assume you were looking to balance the reaction: CH4 + 2O2 --> CO2 +2H2O
A combustion reaction.
The chemical reaction is: CH4 + 2O2 --> 2H2O + CO2 CO2 is the carbon dioxide.
this is an exotermic reaction
CH4 + 2O2 --> CO2 + 2(H2O), the products are CO2 and H2O
Ch4 + 2o2 -> co2 + 2h2o This moron site does not allow capitalization of chemical formulas to be written properly, so all letters here are capitals.
CH4+O2 --- CO2+H2O... All that's missing - is the number 2 before the water molecule... CH4+O2 --- CO2+2H2O
Methane, oxygen, carbon dioxide and water are the four substances.
The oxidizing agent in the reaction CH4 + 2O2 → CO2 + 2H2O is oxygen (O2). Oxygen is the substance that is gaining electrons and causing the methane (CH4) to oxidize.
Unbalanced CH4 + O2 = H2O + CO2 Balanced CH4 + 2O2 = 2H20 + CO2
The product in the reaction of CH4 + 2O2 => CO2 + 2H2O is carbon dioxide (CO2) and water (H2O).
The molecular equation for the combustion of methane gas (CH4) in the presence of oxygen (O2) is: CH4 + 2O2 -> CO2 + 2H2O.
