`C8H18+O2 ------------> CO2+H2O  In balance chemical equation we should equal the no. of atom both sides.EXAMPLE : if we have 8 atom of carbon in reactant it must be equal in product Carbon on left = Carbon on rightNow we come on the equation we have to balanced`
`C8H18+O2 ------------> CO2+H2O put 8 with CO2 to balance carbon`
`C8H18+O2 ------------> 8CO2+H2O (Carbon balanced)`
`put 9 with H2O to balance Hydrogen`
`C8H18 + O2 ------------> 8CO2 + 9H2O  (Hydrogen balanced)Now we solve it according to condition to balanced the oxygen we can change the values or no of atoms of above balanced carbon andhydrogen. put 25 with oxygen for balanced it.`
`2C8H18 +25O2 ------------> 16CO2 + 18H2O`
`this is required balanced equation.we should solve it step by step as above for practice. `
