Balance the following reaction. a coefficient of "1" is understood. choose option "blank" for the correct answer if the coefficient is "1."

c3h8 + o2 → co2 + h2o

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Explanation:

To balance a chemical reaction, we should apply the law of conversation of mass.The law of conversation of mass states that the mass does not destroyed or created from nothing but it van be transformed from one form to another.The no. of atoms in the reactants side must be equal to that in the products side.

So, the balanced equation is: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.

1.0 mole of propane is burned by 5 moles of oxygen to produce 3 moles of carbon dioxide and 4 moles of water.

The correct answer is b.hoped i you
