Respuesta :
CH4+O2 = CO2+2H2O
C-1 C-1
O-2 O-4
H-4 H-4
CH4+2 O2 = CO2+2 H2O
C-1 C-1
O-2-4 O-4
H-4 H-4
You add a 2 in front of the O2 on the reactant side so the Oxygen can balance on the Product side
The given chemical equation has imbalanced oxygen atoms. The balanced chemical equation will be [tex]\rm CH_4\;+\;2\;O_2\;\rightarrow\;CO_2\;+\;2\;H_2O[/tex].
A chemical reaction has been termed as the balanced chemical equation when the stoichiometric coefficient of each element on the product and reactant side has been equal.
In the given chemical equation, the number of atoms of oxygen on the product and the reactant side has been imbalanced. In order to balance the number of oxygen, 2 has been added as the coefficient to the reactant oxygen.
The resultant reaction will have equal oxygen for both the product and the reactant, and thus the reaction has been balanced.
The resultant equation has been;
[tex]\rm CH_4\;+\;2\;O_2\;\rightarrow\;CO_2\;+\;2\;H_2O[/tex]
