After the flip, the volume axis will be lined up end-to-end with the zero values superimposed. you should now have a curve that looks like an "s" lying on its side and one of the graphs will be face down. hopefully your graph paper is "see through." find the ph range over which the buffer effectively neutralizes the added strong acid and strong base and maintains a reasonably constant ph. this is referred to as the buffer range. to which of the following ranges is the buffer range of the acidic buffer closest?

Tell me the iupac name of the following compounds:

Which formula equation represents the burning of sulfur to produce sulfur dioxide? s(s) + o2(g) 4502(9) 2h2s(s) + 302(g) —> 2h20(0) + 2502(9) 4fes2+1102 —> 2fe2o3 + 8502 2802(g) + o2(9) v205 , 2503(9)

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.
