Initial prediction : CH_4+O_2 transfers to CO_2+H_2O
Initial Explanation :
The products of this reaction are CO_2 and H_2O. These elements are Carbon Dioxide and Water. Atom's chemical properties are determined by the number of electrons in its outermost shells. Based on the number of electrons in the shells, it decides the reactivity of atoms. Atoms with the same number of electrons in the outer shells have similar chemical properties. If atoms have 1,2 or 3 valence electrons they react by giving out those electrons to become stable. If atoms have 6 or 7 electrons in the outer shell they react by taking in electrons to complete its outer shell.
So Methane has 8 valence electrons while Oxygen has 6. One molecule of methane combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy.
In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide.The reactants are on the left side of the equation and the products are on the right. In the reaction, the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. No new atoms are created and no atoms are destroyed. This reaction is a combustion reaction.

Revised prediction : CH_4+O_2 transfers to CO_2+H_2O
Revised Explanation : I was correct initially so I put the same explanation.

The reaction as shown is a combustion reaction.
The reaction; CH4 + O2 ---> CO2 + 2H2O2 is a combustion reaction because methane reacts with oxygen to yield carbon dioxide and water. Carbon is always tetravalent in its compounds hence there are four carbon oxygen bonds in the product. Lets recall that the bonds in CH4 re nonpolar because of the minimal electronegativity difference between carbon and hydrogen. Even though the bond in CO2 is polar but the eneitire molecule is nonpolar because the dipoles cancel out. Water is a polar molecule.
Hydrogen forms only one bond hence in water molecule, each hydrogen atom is bonded to a central oxygen atom. All the bonds in water and carbon dioxide as well as in methane and oxygen are covalent.
