An alkyne of six carbon atoms gives the same single product in its reaction either with BH3 in THF followed by H2O2 /OH-, or with H2O/Hg2 /H3O . Draw the structure of the alkyne (containing only carbon and hydrogen atoms).
Determine q for the acid-base reaction, assuming that the liquids have densities of 1.00 g/mL and the same heat capacities as pure water.
Calculate the volume of 1M solution of HCL needed for 1 unit shift of the pH of the following solutions: A. 100 mL of 0.01 M solution weak acid (pKa = 6) and 0.05 M of its sodium salt
that during one such stroke the opposing pressure in the tire was 30.0lb/in2 above the normal atmospheric pressure of 14.7 lb/in2. Calculate the number of joules of work accomplished during each stroke (1 atm= 101.325 J)
