2. why does a diprotic acid dissociate in a stepwise manner? 3. 4 calculate the ph at each of the following points in the titration of 50.00 ml of a 0.150m acetic acid using 0.275m naoh. (show work below: ) (k, 1.8 x 10-5) (you can also refer to pages om your textbook for . initial ph: 0 ml of base added halfway to equivalence point 5.00 ml before equivalence point at equivalence point 5.00 ml beyond equivalence point a. b. c. d. e.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
