The balanced chemical equation is
.
Explicación
## Step 1The given chemical equation is
. This equation represents the combustion of methane (CH4) in the presence of oxygen (O2) to produce water (H2O) and carbon dioxide (CO2).## Step 2To balance this chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. This is in accordance with the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.## Step 3Looking at the equation, we can see that there are 4 hydrogen atoms in CH4 and 2 hydrogen atoms in each H2O molecule. Therefore, we need 2 H2O molecules to balance the hydrogen atoms.## Step 4Now, we have 4 hydrogen atoms on the right side of the equation, but only 1 carbon atom in CH4 and 1 carbon atom in CO2 on the left side. Therefore, the equation is not balanced yet.## Step 5To balance the carbon atoms, we need to have 2 CO2 molecules on the right side of the equation. This gives us 2 carbon atoms on both sides of the equation.## Step 6Finally, we need to balance the oxygen atoms. On the left side, we have 2 oxygen atoms in O2 and 2 oxygen atoms in 2 CO2 molecules, giving us a total of 4 oxygen atoms. On the right side, we have 2 oxygen atoms in 2 H2O molecules and 2 oxygen atoms in 2 CO2 molecules, giving us a total of 4 oxygen atoms.
