When a mole of decane undergoes complete combustion, how many moles of water are formed?

A) 1
B) 10
C) 11
D) 15.5
E) 22

Complete Combustion

A combustion reaction where the fuel is entirely consumed, producing only carbon dioxide, water, and energy, assuming ample oxygen supply.

Decane

A saturated hydrocarbon with the formula C10H22, consisting of a chain of ten carbon atoms.

Moles

A unit of measurement used in chemistry to express amounts of a chemical substance, defined as the amount of any substance that contains as many elementary entities as there are atoms in 12 grams of pure carbon-12.

Final Answer :
C
Explanation :
The balanced chemical equation for the combustion of decane is:
C10H22 + 13O2 → 10CO2 + 11H2O
From the equation, we can see that 1 mole of decane reacts with 13 moles of oxygen gas to form 11 moles of water. Therefore, when 1 mole of decane undergoes complete combustion, 11 moles of water are formed.
