Write the balanced chemical equation for ethanol C2H6O burning in air as a LEAN mixture if the reactant side of the reaction is C₂H₆O + ?(O₂ + 3.76N₂) ===> ? CO₂ + H2O + ? ?????

NOTE: A LEAN mixture means you have more air than you need to burn all the fuel. You will have excess oxygen left over after the reaction process.

Expert Solution

Answer -

We are given the ethanol and it is burn in the air and ask for the complete the reaction of combustion reaction

C₆H₆O + (O₂ + 3.76 N₂)-----> CO₂ + H₂O + N₂

C = 6 C = 6

H = 6 H = 2

O = 3 O = 3

N = 7.52 N = 2

C₆H₆O + 14/2 (O₂ + 3.76 N₂)-----> 6CO₂ + 3H₂O +26.32 N₂

Now we need to multiply by 2

2 C₆H₆O + 14 (O₂ + 3.76 N₂)-----> 12 CO₂ + 6 H₂O +52.64 N₂

So this is the balanced equation.
