8. A student is conducting an experiment where they poured clear Silver Nitrate (AgNO3) and clear Sodium Chloride (NaCl(aq)) solution together. They recorded the following observations: the beaker became warm, the solution turned white because there was a precipitate that formed. Did a chemical reaction occur? Make a claim and provide evidence that supports whether a reaction took place or not. Once you have done that include your reasoning to support your claim and evidence

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.
