Question

Determine the balanced chemical equation for this reaction. C8H18(g)+O2(g)→CO2(g)+H2O(g)

Answer 1

Answer: balanced reaction equation

C8H18(g) + 25/2 O2(g) ---------> 8CO2(g) + 9H2O(l)

Explanation:

Part A- coefficients

1, 25/2,8,9

Part B

Oxygen is the limiting reactant

Part C

If 1 mole of octane produced 9 moles of water from the balanced reaction equation

0.28 moles of octane will produce 0.28×9= 2.52 moles of water

Part D

If 12.5 moles of oxygen reacts with 1 mole of octane

0.63 moles of oxygen will react with 0.63/12.5=0.0504moles of octane

Amount of octane left= 0.280-0.0504=0.2296 moles
