Carbon dioxide and water are produced when pentane (c5h12) reacts with oxygen. What is the balanced equation for this reaction? c5h12(g) + o2(g) → co2(g) + h2o(g) c5h12(g) + o2(g) → 5co2(g) + h2o(g) c5h12(g) +8o2(g) → 5co2(g) + 6h2o(g) 5co2(g) + 6h2o(g) → c5h12(g) + 8o2(g) c5h12(g) +5o2(g) → 5co2(g) + 6h2(g) ch2(g) +o2(g) → co2(g) + h2(g).
