Answer:

204 moles of water and 192 moles of carbon dioxide.

Step-by-step 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.
