Answer:

B. C7H16 + 11O2 → 7CO2 + 8H2O

Explanation:

  • In a balanced chemical equation, the number of atoms of each element is equal on both sides of the equation.
  • In this case, the balanced chemical equation is;

   C7H16 + 11O2 → 7CO2 + 8H2O

Because, it has 7 carbon atoms, 16 hydrogen atoms and 22 oxygen atoms on each side of the equation.

  • When an equation is balanced it obeys the law of conservation of mass such that the mass of reactants will be equal to the mass of products.

Answer:

B. C7H16 + 11O2 → 7CO2 + 8H2O
