A standard galvanic cell is constructed with Sn2+ | Sn and Cu2+ | Cu half cell compartments connected by a salt bridge. Which of the following statements are correct? (Choose all that apply.) 1. In the external circuit, electrons flow from the Cu2+|Cu compartment to the Sn2+|Sn compartment.
2. The anode compartment is the Sn2+|Sn compartment.
3. The cathode compartment is the Sn2+|Sn compartment.
4. As the cell runs, anions will migrate from the Cu2+|Cu compartment to the Sn2+|Sn compartment.
5. Cu2+ is reduced at the cathode.

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.
