The balanced chemical equation for the combustion of octane is: 2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O From the equation, 1 mole of octane produces 16 moles of CO2. Therefore, 15.0 g of octane will produce 15.0 g x (16/114.20) = 2.10 g of CO2 when burned with 15.0 g of oxygen gas.
6,49 moles of water are obtained.
Octane is a compound. octane + O2 = CO2 + H2O + Energy, You can tell by the inputs and outputs. Octane and Oxygen inputs and Carbon dioxide and water outputs, means Octane must consist of hydrogen H and carbon C, thus a compound not an element.
First write down the BALANCED reaction eq'n. Octane + oxygen = Water + Carbon Dioxide. 2CH3(CH2)6CH3 + 25O2 = 18H2O + 16CO2 The molar ratios are 2:25 :: 18:16 So '2' moles of octane produces 18 moles of water. So by equivlance 0.468 : x :: 2 : 18 Algebraically rearrgange x = (0.468/2) X 18 => x = 0.234 x 18 = > x = 4.212 moles water produces.
For every molecule of octane burned, 8 molecules of carbon dioxide are produced in a balanced reaction for the complete combustion of octane.

The two products of the complete combustion of octane are carbon dioxide (CO2) and water (H2O).
Octane + oxygen ---> carbon dioxide + water Lulu
When octane is burned, it releases energy in the form of heat. This energy is typically measured in units of kilojoules per mole of octane burned. The energy released during combustion of octane is used to power engines and vehicles.

This is a typical combustion reaction in that it involves a hydrocarbon reacting with oxygen. The products of combustion reactions are always carbon dioxide and water, just in varying quantities.
