If you answer correctly i'll give you brainliest! i need the correct answer or else i'll get a 75 at most! there's only 4 questions on my assignment! what type of nuclear reaction results in a single nucleus undergoing a decrease in mass number, a decrease in atomic number, and the release of a helium nucleus? a. alpha decay b. beta decay c. gamma radiation d. nuclear fusion

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.
