The given equation is as
C2H5OH + 3O2 --> 2CO2 + 3H2O
No. of atoms of each elements are as
| Reactants | Products |
| No. of carbon atoms = 2 | No. of carbon atoms = 2 |
| No. of hydrogen atoms = 5 + 1 = 6 | No. of hydrogen atoms = 2 x 3 = 6 |
| No. of oxygen atoms = 3 x 2 + 1 = 7 | No. of oxygen atoms = 2 x 2 + 3 = 7 |
In both sides of the reaction, no. of atoms of each elements are same. Therefore, the given reaction is balanced.

The chemical reaction equation of Combustion of Ethanol is given as below X1C2H5OH + X202 → X3C02 + x4H20 This chemical reaction consist of three elements: Carbon(C); Hydrogen(H); Oxygen(O). The subscripts on the elements indicate the number of atoms. (No subscript indicates one atom.) Balancing the equation involves finding values for X1, X2, X3, and X4 so that the number of atoms of each element is the same before and after the reaction.

When a chemical reaction occurs, atoms rearrange to form now compounds, but no new atoms are created nor are any destroyed This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (tan spheres). Write the balanced chemical equation for this...
