Carbon dioxide and water are produced when pentane (C3H12) reacts with oxygen. What is the balanced equation for this reaction?
O C5H12(g) + O2(g) - CO2(g) + H2O(g)
OCH 12(g) + O2(g) - 5CO2(g) + H2O(g)
O C5H12(g) +8O2(g) - 5C02(g) + 6H2O(g)
O 5C02(g) + 6H2O(g) - C5H12(g) + 80260)
C5H12(g) +502(g) - 5CO2(g) + 6H2(0)
O CH2(g) +O2(g) → CO2(g) + H269)
