9. If we start with 12 moles of diesel (C16H34), how many moles of water and

carbon dioxide will be produced in a complete combustion reaction?

204 moles of water and 192 moles of carbon dioxide.

Explanation: The complete combustion of hydrocarbons results to the formation of water and carbon dioxide as the products. Diesel is an example of a hydrocarbon whose combustion will yield water and carbon dioxide. The equation for the combustion of diesel is given by;

2C₁₆H₃₄ + 49O₂ → 32CO₂ + 34H₂O

We are given 12 moles of diesel

Required to determine the number of moles of water and carbon dioxide.

From the equation;

2 moles of diesel reacts to generate 32 moles of carbon dioxide and 34 moles of water.

Therefore;

Moles of water = moles of diesel * 34/2

= 12 moles * 34/2

= 204 moles

Moles of Carbon dioxide = Moles of diesel * 32/2

= 12 moles * 32/2

= 192 moles

Therefore, the combustion of 12 moles of diesel yields 204 moles of water and 192 moles of carbon dioxide.
