Question

how to balance this equation ? CH4+O2 = Co2+H2O

Answer 1

CH4+2O2=CO2+2H2O....M

Answer 2

Balancing equation

Explanation:

• In the given reaction, methane is reacting with oxygen to produce carbon dioxide and water.

• The chemical equation involved is

$CH_4+O_2\rightarrow CO_2+H_2O$

• When the number of atoms for the reactant side is calculated it gives:

C = 1

H = 4

O = 2

• When the number of atoms for the product side is calculated it gives:

C = 1

H = 2

O = 3

• The obtained result indicates that the atoms of hydrogen and oxygen are not equal on both sides. Thus the reaction is not balanced.
• The balanced reaction has the number of atoms involved in reaction in reactants as well as the product is equal.
• To make both side equal some changes must be made as shown in the balanced equation is

$CH_4+2O_2\rightarrow CO_2+2H_2O$

• For the above equation, the number of atoms in the reactants is:

C = 1

H = 4

O = 4

• The number of atoms in products is:

C = 1

H = 4

O = 4

• As the number of atoms in the reactants side is equal to the number of atoms in the product side, the reaction is balanced.
