Determine the reaction equation and molal air/fuel ratio for the combustion of ethyl alcohol, C2H5 (OH) , with
a. 100.% theoretical air.
b. 100.% excess air.
c. 50.0% deficit air.
Find the mechanism for problem 1 and then find the equilibrium constant for the first step of the mechanism and then find a more favorable deprotonation step.
25 mL of an unknown Ba(OH)2 solution require 20 mL of a .150M HCl solution to neutralize it: Ba(OH)2 (aq)+ 2HCl (aq) -> 2H2O (l) + BaCl2 (aq) 1) How many moles of HCl were used in the titration?
