Balance the Following C₇H₁₆ + O₂ ---> CO₂ + H₂0

C₇ H₁₆   +   11O₂    →   7CO₂     +    8H₂O

Explanation:

Given equation

       C₇ H₁₆   +   O₂   →   CO₂    +    H₂O

To solve this problem,

 We use a mathematical approach to balance the equation:

             aC₇ H₁₆   +   bO₂    →   cCO₂     +    dH₂O

Conserving C; 7a = c

                   H ; 16a  = 2d

                   O: 2b  = 2c + d

Let a  = 1

     c  = 7

    d  = 8

    b  = 11

Now insert the parameters and solve;

      C₇ H₁₆   +   11O₂    →   7CO₂     +    8H₂O

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
