CH_(3)CH_(2)l reacts more rapidly with strong base in comparison to CD_(3)CH_(2)l . Explain

0.5 L of 0.5 M CH_(3)COOH and 0.5 L of 0.25 M CH_(3)COONa are available. What maximum volume of a buffer with a pH =4.58 can be prepared using only these two resources ? K_(a) =1.8xx10^(-5)

Under identical conditions of pressure and temperature, 4 L of gaseous moxture ( H_(2) and CH_(4) ) effuses through a hole in 5 min whereas 4 L of a gas X of molecular mass 36 takes to 10 min to effuse through the same hole. The mole ratio of H_(2):CH_(4) in the mixture is:
