According to the bohr model of an atom, what happens when an electron moves from the second energy level to the third energy level and then back to the second energy level? energy is absorbed and then stored in the atom. energy is released and then absorbed to form an absorption line. energy is absorbed and then released to form an emission line. energy is released from the atom, and the outer level is weakened.

1) describe the physical layout of the ocean floor ? 2) explain how the dumbo octopus swims differently than other octopus species and why this would be an advantage in the aphonic zone . 3) why are the types of organisms that live at each underwater hot vent so dramatically different ?

Which of the following is a physical property flammability heat of combustion solubility and toxicity

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.
