The images show two different fronts. Item A: A cold front and warm front meet with high level, grey clouds. Item B: Warm air is above cold and very cold air, lower clouds with rain falling. Which fronts are shown? Item A shows a cold front, and item B shows a warm front. Item A shows an occluded front, and item B shows a cold front. Item A shows a warm front, and item B shows a stationary front. Item A shows a stationary front, and item B shows an occluded front.

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?

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.
