Ihave this question for homework. but balancing chemical equations has never been my strong point can somebody explain it to me ?
3. when propane burns in air, it reacts with
oxygen (o2) to form carbon dioxide (co)
and water (h2o). which balanced chemical
equation describes this reaction?
a. c3hg + o2 + co2 + h2o
b. c3h8 + 402 co2 + 4h2o
c. c3h3 + 502 3c02 + h2o
d. c3hg + 502 → 3co2 + 4h2o
