Question

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?​

Answer 1

Answer:

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.
