If a steel nail is wrapped 8 times with an insulated copper wire and each end of is attached to a 1.5 V battery, we find that it will lift the weight of 2 large paper clips. We hypothesized that for each 8 coils, you will be able to pick up one additional paper clip. When we ran the experiment, we observed and recorded that when we added 8 more wraps around the nail (16 coils) we could lift 4 paper clips and when we added 8 more wraps (24 coils) we could lift 6 paper clips. Choose the correct conclusion to the experiment. 1. We concluded that something went wrong with the experiment since it didn't give us the results we expected. 2. We redesign the test and hope for better results. 3. We concluded that our original test flawed. Because of the results, 8 coils should be able to pick up 2 paper clips. We will check our original test with a fresh battery. 4. We concluded that every time we add 8 wraps to the nail the total number of paper clips lifted doubled.

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.
