100 cm³ of 2.0 mol dm‐³ hydrochloric acid is poured into 100 cm³ of 2.0 mol dm‐³ sodium hydroxide solution. The initial and final temperature are immediately recorded as shown below. [Specific heat capacity = 4.2 J/g°C, density of solution = 1.0 gcm-3]. What is the value of heat released in the reaction? initital temperature of hydrochloric acid: 29.0°C

initial temperature of sodium hydroxide solution: 29.0°C

highest temperature of the mixture: 35.0°C

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.
