Question

If 2 moles of each of the following fuel undergoes combustion, which will yield the greatest amount of carbon dioxide?

a. Ethanal
b. 3-pentanone
c. 2-butanone
d. To difficult to figure out.

Answer 1

The answer to your question is: 3-pentanone produces the greatest amount of carbon dioxide

Step-by-step explanation:

a) Ethanal

2C₂H₁₀O + 5O₂ ⇒ 4CO₂ + 4H₂O

2 moles of ethanal produces 4 moles of carbon dioxide

b) 3-Pentanone

C₅H₁₀O + 7O₂ ⇒ 5CO₂ + 5H₂O

2 moles of 3-pentanone produces 10 moles of carbon dioxide

c) 2-Butanone

2C₄H₈O + 11O₂ ⇒ 8CO₂ + 8H₂O

2 moles of 2-butanone produce 8 moles of carbon dioxide
