Compute the pH after 0.015 mole of gaseous HCl is added to 274.0 mL of each of the subsequent buffered solutions. Presume that all solutions are at 25°C.
(a) 0.087 M C5H5N and 0.17 M C5H5NHCl
(b) 0.75 M C5H5N and 1.53 M C5H5NHCl
Two molecules of 1,3-butadiene (C4H6) react to form 1,5-cyclooctadiene (C8H12). As the Reaction proceeds, the pressure in the container falls, because two gas molecules are consumed to produce one product molecule.
